 .Dt RTLD_GET_VAR 3
 .Os
 .Sh NAME
 .Nm rtld_get_var ,
 .Nm rtld_set_var
 .Nd query or change run-time linker parameters after image activation
 .Sh LIBRARY
 .Lb libc
 .Sh SYNOPSIS
 .In sys/errno.h
 .In link.h
 .Ft const char *
 .Fn rtld_get_var "const char *name"
 .Ft int
 .Fn rtld_set_var "const char *name" "const char *value"
 .Sh DESCRIPTION
 The dynamic linker
 .Xr rtld 1
-can be configured be setting some environment variables for the process,
+can be configured by setting some environment variables for the process,
 before image activation.
 Sometimes it is desirable to query the current effective settings or
 change them afterward.
 .Pp
 Since the process environment variables are maintained by higher-level
 libraries, the run-time linker cannot access them after the image
 activation.
 The described functions make it possible to operate on rtld settings.
 .Pp
 The
 .Fn rtld_get_var
 function returns the current value of the named parameter.
 .Pp
 The
 .Fn rtld_set_var
 functions changes the value of the parameter to the new
 .Fa value
 value, if possible.
 The
 .Fa name
 argument to both functions is the name of the parameter, which
 is same as the corresponding environment variable
 .Pq see Xr rtld 1
 but without the
 .Ev LD_
 (or
 .Ev LD_32_
 or any other ABI-specific) prefix.
 .Sh RETURN VALUES
 The
 .Fn rtld_get_var
 returns the current value of the named parameter, or
 .Dv NULL
 if the name is invalid.
 .Pp
 The
 .Fn rtld_set_var
 returns 0 on success, or an integer indicating the error condition
 which prevented the operation.
 .Sh ERRORS
 Possible errors returned from
 .Fn rtld_set_var :
 .Bl -tag -width Er
 .It Bq Er EPERM
 The requested change cannot be made at runtime, either because the
 runtime linker can only take this parameter at initialization time,
 or because the current process is executing with elevated privileges.
 .It Bq ENOENT
 The supplied parameter
 .Fa name
 is unknown.
