#include <sys/stat.h> #ifndef _S_ISTYPE #define _S_ISTYPE(mode, mask) (((mode) & _S_IFMT) == (mask)) #define S_ISREG(mode) _S_ISTYPE((mode), _S_IFREG) #define S_ISDIR(mode) _S_ISTYPE((mode), _S_IFDIR) #endif
ExampleUse() { struct sb sb; char *pathname = "c:/windows"; if (stat(pathname, &sb) == -1) { // It does not exist (or other less common problem) return; } if (S_ISREG(sb.st_mode)) { // Its a regular file } if (S_ISDIR(sb.st_mode)) { // Its a directory } }
