What I have to put as second parameter in this function? I need to understand the meaning of int (*fn)(const char *, const struct stat *ptr, int flag).
int ftw(const char *path, int (*fn)(const char *, const struct stat *ptr, int flag), int depth); Thank you!!
int (*fn)(const char *, const struct stat *ptr, int flag) is a pointer to a function that returns an int and takes a const char*, a const struct stat *, and an int.
If you had this function:
int func (const char *s, const struct stat *ptr, int flag) { return 0; } You could pass func as that argument.
