readlink(2) -- Linux man page
NAME
readlink - read value of a symbolic link
SYNOPSIS
#include <unistd.h>
int readlink(const char *path, char *buf, size_t bufsiz);
DESCRIPTION
readlink
places the contents of the symbolic link
path
in the buffer
buf,
which has size
bufsiz.
readlink
does not append a
NUL
character to
buf.
It will truncate the contents (to a length of
bufsiz
characters), in case the buffer is too small to hold all of the contents.
RETURN VALUE
The call returns the count of characters placed in the buffer
if it succeeds, or a -1 if an error occurs, placing the error
code in
errno.
