How to delete a directory and its contents in (POSIX) C? [duplicate]

Answer 1

Use the nftw() (File Tree Walk) function, with the FTW_DEPTH flag. Provide a callback that just calls remove() on the passed file:

#define _XOPEN_SOURCE 500
#include 
#include 
#include 

int unlink_cb(const char *fpath, const struct stat *sb, int typeflag, struct FTW *ftwbuf)
{
    int rv = remove(fpath);

    if (rv)
        perror(fpath);

    return rv;
}

int rmrf(char *path)
{
    return nftw(path, unlink_cb, 64, FTW_DEPTH | FTW_PHYS);
}
