FILENAME_MAX
Maximum length of file names
This macro constant expands to an integral expression corresponding to the size needed for an array of char elements to hold the longest file name string allowed by the library. Or, if the library imposes no such restriction, it is set to the recommended size for character arrays intended to hold a file name.
