passing glob an argument in GCC

0 votes
46 views

Hi, I'm uncertain what an argument to glob should be.

int glob (const char *pattern, int flags, int (*errfunc) (const char
*filename, int error-code), glob_t *vector-ptr)

It takes a pointer to a function called errfunc. Now I've read the docs but
they give no mention of a function called errfunc, so I think I have to
write it myself. What should it look like? What should it do?

glob() is not part of GCC and assuming your question is not about GCC.

The glob(3) man page explains it clearly. errfunc is not a function that exists already, it's the name of one of the parameters in the glob prototype, you have to pass an argument (or NULL) matching the signature:
int (*errfunc) (const char *epath, int eerrno)
