C语言检测对象是文件还是文件夹
bool file_exists ( const char * Pathname ) /* is there a regular file by the name of Pathname. */ { bool Exists; struct stat Info; if (stat(Pathname, &Info) == 0) { Exists = S_ISREG(Info.st_mode); } else { Exists = false; } /*if*/ return Exists; } /*file_exists*/
检测是否是文件夹
bool directory_exists ( const char * Pathname, bool FollowSymlink /* true to return true if Pathname is a symlink to a directory, false to return false for a symlink */ ) /* is there a directory by the name of Pathname. */ { bool Exists; struct stat Info; if ( (FollowSymlink ? stat(Pathname, &Info) : lstat(Pathname, &Info) ) == 0 ) { Exists = S_ISDIR(Info.st_mode); } else { Exists = false; } /*if*/ return Exists; } /*directory_exists*/
