+.Sh DESCRIPTION
+The
+.Nm libnv
+library allows to easily manage name value pairs as well as send and receive
+them over sockets.
+A group (list) of name value pairs is called an
+.Nm nvlist .
+The API supports the following data types:
+.Bl -ohang -offset indent
+.It Sy null ( NV_TYPE_NULL )
+There is no data associated with the name.
+.It Sy bool ( NV_TYPE_BOOL )
+The value can be either
+.Dv true
+or
+.Dv false .
+.It Sy number ( NV_TYPE_NUMBER )
+The value is a number stored as
+.Vt uint64_t .
+.It Sy string ( NV_TYPE_STRING )
+The value is a C string.
+.It Sy nvlist ( NV_TYPE_NVLIST )
+The value is a nested nvlist.
+.It Sy descriptor ( NV_TYPE_DESCRIPTOR )
+The value is a file descriptor.
+Note that file descriptors can be sent only over
+.Xr unix 4
+domain sockets.
+.It Sy binary ( NV_TYPE_BINARY )
+The value is a binary buffer.
+.It Sy bool array ( NV_TYPE_BOOL_ARRAY )
+The value is an array of boolean values.
+.It Sy number array ( NV_TYPE_NUMBER_ARRAY )
+The value is an array of numbers, each stored as
+.Vt uint64_t .
+.It Sy string array ( NV_TYPE_STRING_ARRAY )
+The value is an array of C strings.
+.It Sy nvlist array ( NV_TYPE_NVLIST_ARRAY )
+The value is an array of nvlists.
+When an nvlist is added to an array, it becomes part of the primary nvlist.
+Traversing these arrays can be done using the
+.Fn nvlist_get_array_next
+and
+.Fn nvlist_get_pararr
+functions.
+.It Sy descriptor array ( NV_TYPE_DESCRIPTOR_ARRAY )
+The value is an array of files descriptors.
+.El
+.Pp
+The
+.Fn nvlist_create
+function allocates memory and initializes an nvlist.
+.Pp
+The following flag can be provided:
+.Pp
+.Bl -tag -width "NV_FLAG_IGNORE_CASE" -compact -offset indent
+.It Dv NV_FLAG_IGNORE_CASE
+Perform case-insensitive lookups of provided names.
+.It Dv NV_FLAG_NO_UNIQUE
+Names in the nvlist do not have to be unique.
+.El
+.Pp
+The
+.Fn nvlist_destroy
+function destroys the given nvlist.
+Function does nothing if
+.Dv NULL
+nvlist is provided.
+Function never modifies the
+.Va errno
+global variable.
+.Pp
+The
+.Fn nvlist_error
+function returns any error value that the nvlist accumulated.
+If the given nvlist is
+.Dv NULL
+the
+.Er ENOMEM
+error will be returned.
+.Pp
+The
+.Fn nvlist_set_error
+function sets an nvlist to be in the error state.
+Subsequent calls to
+.Fn nvlist_error
+will return the given error value.
+This function cannot be used to clear the error state from an nvlist.
+This function does nothing if the nvlist is already in the error state.
+.Pp
+The
+.Fn nvlist_empty
+function returns
+.Dv true
+if the given nvlist is empty and
+.Dv false
+otherwise.
+The nvlist must not be in error state.
+.Pp
+The
+.Fn nvlist_flags
+function returns flags used to create the nvlist with the
+.Fn nvlist_create
+function.
+.Pp
+The
+.Fn nvlist_in_array
+function returns
+.Dv true
+if
+.Fa nvl
+is part of an array that is a member of another nvlist.
+.Pp
+The
+.Fn nvlist_clone
+functions clones the given nvlist.
+The clone shares no resources with its origin.
+This also means that all file descriptors that are part of the nvlist will be
+duplicated with the
+.Xr dup 2
+system call before placing them in the clone.
+.Pp
+The
+.Fn nvlist_dump
+dumps nvlist content for debugging purposes to the given file descriptor
+.Fa fd .
+.Pp
+The
+.Fn nvlist_fdump
+dumps nvlist content for debugging purposes to the given file stream
+.Fa fp .
+.Pp
+The
+.Fn nvlist_size
+function returns the size of the given nvlist after converting it to binary
+buffer with the
+.Fn nvlist_pack
+function.
+.Pp
+The
+.Fn nvlist_pack
+function converts the given nvlist to a binary buffer.
+The function allocates memory for the buffer, which should be freed with the
+.Xr free 3
+function.
+If the
+.Fa sizep
+argument is not
+.Dv NULL ,
+the size of the buffer will be stored there.
+The function returns
+.Dv NULL
+in case of an error (allocation failure).
+If the nvlist contains any file descriptors
+.Dv NULL
+will be returned.
+The nvlist must not be in error state.
+.Pp
+The
+.Fn nvlist_unpack
+function converts the given buffer to the nvlist.
+The
+.Fa flags
+argument defines what type of the top level nvlist is expected to be.
+Flags are set up using the
+.Fn nvlist_create
+function.
+If the nvlist flags do not match the flags passed to
+.Fn nvlist_unpack ,
+the nvlist will not be returned.
+Every nested nvlist list should be checked using
+.Fn nvlist_flags
+function.
+The function returns
+.Dv NULL
+in case of an error.
+.Pp
+The
+.Fn nvlist_send
+function sends the given nvlist over the socket given by the
+.Fa sock
+argument.
+Note that nvlist that contains file descriptors can only be send over
+.Xr unix 4
+domain sockets.
+.Pp
+The
+.Fn nvlist_recv
+function receives nvlist over the socket given by the
+.Fa sock
+argument.
+The
+.Fa flags
+argument defines what type of the top level nvlist is expected to be.
+Flags are set up using the
+.Fn nvlist_create
+function.
+If the nvlist flags do not match the flags passed to
+.Fn nvlist_recv ,
+the nvlist will not be returned.
+Every nested nvlist list should be checked using
+.Fn nvlist_flags
+function.
+.Pp
+The
+.Fn nvlist_xfer
+function sends the given nvlist over the socket given by the
+.Fa sock
+argument and receives nvlist over the same socket.
+The
+.Fa flags
+argument defines what type of the top level nvlist is expected to be.
+Flags are set up using the
+.Fn nvlist_create
+function.
+If the nvlist flags do not match the flags passed to
+.Fn nvlist_xfer ,
+the nvlist will not be returned.
+Every nested nvlist list should be checked using
+.Fn nvlist_flags
+function.
+The given nvlist is always destroyed.
+.Pp
+The
+.Fn nvlist_next
+function iterates over the given nvlist returning names and types of subsequent
+elements.
+The
+.Fa cookiep
+argument allows the function to figure out which element should be returned
+next.
+The
+.Va *cookiep
+should be set to
+.Dv NULL
+for the first call and should not be changed later.
+Returning
+.Dv NULL
+means there are no more elements on the nvlist.
+The
+.Fa typep
+argument can be NULL.
+Elements may not be removed from the nvlist while traversing it.
+The nvlist must not be in error state.
+Note that
+.Fn nvlist_next
+will handle
+.Va cookiep
+being set to
+.Dv NULL .
+In this case first element is returned or
+.Dv NULL
+if nvlist is empty.
+This behavior simplifies removing the first element from the list.
+.Pp
+The
+.Fn nvlist_exists
+function returns
+.Dv true
+if element of the given name exists (besides of its type) or
+.Dv false
+otherwise.
+The nvlist must not be in error state.
+.Pp
+The

+When adding string or binary buffor the functions will allocate memory
+and copy the data over.
+When adding nvlist, the nvlist will be cloned and clone will be added.
+When adding descriptor, the descriptor will be duplicated using the
+.Xr dup 2
+system call and the new descriptor will be added.
+The array functions will fail if there are any
+.Dv NULL
+elements in the array, or if the array pointer is
+.Dv NULL .
+If an error occurs while adding new element, internal error is set which can be

+unique, or it could cause a double free.
+The array functions will fail if there are any

+functions return the value that corresponds to the given key name.
+In the case of strings, nvlists, descriptors, binary, or arrays, the returned
+resource should not be modified - they still belong to the nvlist.
+If an element of the given name does not exist, the program will be aborted.
+To avoid this, the caller should check for the existence of the name before
+trying to obtain the value, or use the
+.Xr dnvlist 3
+extension, which can provide a default value in the case of a missing element.
+The nvlist must not be in error state.
+.Pp
+The
+.Fn nvlist_get_parent
+function returns the parent nvlist of the nested nvlist.
+.Pp
+The
+.Fn nvlist_get_array_next
+function returns the next element from the array or

+In the case of descriptors, the caller is responsible for closing every
