How do i check in C++ if a file is a regular file (and is not a directory, a pipe, etc.)? I need a function isFile().
DIR *dp;
struct dirent *dirp;
while ((dirp = readdir(dp)) != NULL) {
if ( isFile(dirp)) {
cout << "IS A FILE!" << endl;
i++;
}
I've tried comparing dirp->d_type with (unsigned char)0x8, but it seems not portable through differents systems.
You need to call stat(2) on the file, and then use the S_ISREG macro on st_mode.
Something like (adapted from this answer):
#include <sys/stat.h>
struct stat sb;
if (stat(pathname, &sb) == 0 && S_ISREG(sb.st_mode))
{
// file exists and it's a regular file
}
