READLINK(2) FreeBSD System Calls Manual READLINK(2) NAME readlink -- read value of a symbolic link SYNOPSIS #include <unistd.h> int readlink(const char *path, char *buf, int bufsiz); DESCRIPTION Readlink() places the contents of the symbolic link path in the buffer buf, which has size bufsiz. The readlink() function does not append a NUL character to buf. RETURN VALUES The call returns the count of characters placed in the buffer if it suc- ceeds, or a -1 if an error occurs, placing the error code in the global variable errno. ERRORS Readlink() will fail if: [ENOTDIR] A component of the path prefix is not a directory. [ENAMETOOLONG] A component of a pathname exceeded 255 characters, or an entire path name exceeded 1023 characters. [ENOENT] The named file does not exist. [EACCES] Search permission is denied for a component of the path prefix. [ELOOP] Too many symbolic links were encountered in translating the pathname. [EINVAL] The named file is not a symbolic link. [EIO] An I/O error occurred while reading from the file system. [EFAULT] Buf extends outside the process's allocated address space.
