READLINK(2) BSD System Calls Manual READLINK(2)
NAME
readlink -- read value of a symbolic link
SYNOPSIS
#include <unistd.h>
ssize_t
readlink(const char *restrict path, char *restrict buf, size_t bufsize);
DESCRIPTION
Readlink() places the contents of the symbolic link path in the buffer buf, which has size bufsize. Readlink does not append a NUL character
to buf.
RETURN VALUES
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 the
global variable errno.
ERRORS
Readlink() will fail if:
[EACCES] Search permission is denied for a component of the path prefix.
[EFAULT] Buf extends outside the process's allocated address space.
[EINVAL] The named file is not a symbolic link.
[EIO] An I/O error occurred while reading from the file system.
[ELOOP] Too many symbolic links are encountered in translating the pathname. This is taken to be indicative of a looping symbolic
link.
[ENAMETOOLONG] A component of a pathname exceeded {NAME_MAX} characters, or an entire path name (possibly expanded by a symbolic link)
exceeded {PATH_MAX} characters.
[ENOENT] The named file does not exist.
[ENOTDIR] A component of the path prefix is not a directory.
LEGACY SYNOPSIS
#include <unistd.h>
int
readlink(const char *path, char *buf, int bufsize);
The function type and the type of bufsize have changed.
SEE ALSO
lstat(2), stat(2), symlink(2), compat(5), symlink(7)
HISTORY
The readlink() function call appeared in 4.2BSD.
