READLINK(2) UNIX Programmer's Manual READLINK(2) NNAAMMEE readlink - read value of a symbolic link SSYYNNOOPPSSIISS cccc == rreeaaddlliinnkk((ppaatthh,, bbuuff,, bbuuffssiizz)) iinntt cccc;; cchhaarr **ppaatthh,, **bbuuff;; iinntt bbuuffssiizz;; DDEESSCCRRIIPPTTIIOONN _R_e_a_d_l_i_n_k places the contents of the symbolic link _n_a_m_e in the buffer _b_u_f, which has size _b_u_f_s_i_z. The contents of the link are not null terminated when returned. RREETTUURRNN VVAALLUUEE 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 _e_r_r_n_o. EERRRROORRSS _R_e_a_d_l_i_n_k will fail and the file mode will be unchanged if: [ENOTDIR] A component of the path prefix is not a directory. [EINVAL] The pathname contains a character with the high-order bit set. [ENAMETOOLONG] A component of a pathname exceeded 255 char- acters, 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] _B_u_f extends outside the process's allocated address space.
