 .Sh DESCRIPTION
 The
 .Nm caph_enter
 is equivalent to the
 .Xr cap_enter 2
 it returns success when the kernel is built without support of the capability
 mode.
 .Pp
 The
 .Nm caph_enter_casper
 is equivalent to the
 .Nm caph_enter
 it returns success when the system is built without Casper support.
 .Pp
 The
 .Nm capsicum helpers
 are a set of a inline functions which simplify modifying programs to use
 Capsicum.
 The goal is to reduce duplicated code patterns.
 The
 .Nm capsicum helpers
 are part of
 .Nm libcapsicum
 but there is no need to link to the library.
 .Pp
 .Fn caph_limit_stream
 restricts capabilities on
 .Fa fd
 to only those needed by POSIX stream objects (that is, FILEs).
 .Pp
 These flags can be provided:
 .Pp
 .Bl -tag -width "CAPH_IGNORE_EBADF" -compact -offset indent
 .It Dv CAPH_IGNORE_EBADF
 Do not return an error if file descriptor is invalid.
 .It Dv CAPH_READ
 Set CAP_READ on limited descriptor.
 .It Dv CAPH_WRITE
 Set CAP_WRITE on limited descriptor.
 .El
 .Pp
 .Fn caph_limit_stdin ,
 .Fn caph_limit_stderr
 and
 .Fn caph_limit_stdout
 limit standard descriptors using the
 .Nm caph_limit_stream
 function.
 .Pp
 .Fn caph_limit_stdio
 limits stdin, stderr and stdout.
 .Pp
 .Fn caph_cache_tzdata
 precaches all timezone data needed to use
 .Li libc
 local time functions.
 .Pp
 .Fn caph_cache_catpages
 caches Native Language Support (NLS) data.
 NLS data is used for localized error printing by
 .Xr strerror 3
 and
 .Xr err 3 ,
 among others.
