НАЗВАНИЕ

       canonicalize_file_name - return the canonicalized absolute
       pathname

БИБЛИОТЕКА

       Standard C library (libc, -lc)

СИНТАКСИС

       #define _GNU_SOURCE         /* See feature_test_macros(7) */
       #include <stdlib.h>

       char *canonicalize_file_name(const char *path);

ОПИСАНИЕ

       The canonicalize_file_name() function returns a null-terminated
       string containing the canonicalized absolute pathname
       corresponding to path.  In the returned string, symbolic links
       are resolved, as are .  and ..  pathname components.  Consecutive
       slash (/) characters are replaced by a single slash.

       The returned string is dynamically allocated by
       canonicalize_file_name() and the caller should deallocate it with
       free(3) when it is no longer required.

       The call canonicalize_file_name(path) is equivalent to the call:

           realpath(path, NULL);

ЗНАЧЕНИЕ ВОЗВРАТА

       On success, canonicalize_file_name() returns a null-terminated
       string.  On error (e.g., a pathname component is unreadable or
       does not exist), canonicalize_file_name() returns NULL and sets
       errno to indicate the error.

ОШИБКИ

       See realpath(3).
