function to split a filepath into path and file

Question

Lets say I have a function:

void split_path_file(char** p, char** f, char *pf)
{
    //malloc and set *p to file path, malloc and set *f to file name
    //p         


        

Answer 1

I came up with the following, of course this assumes that pf is malloced.

void split_path_file(char** p, char **f, char *pf)
{
    char *posp = strrchr(pf, '\\');
    *posp = '\0';
    *p = strdup(pf);
    *f = strdup(posp+1);
    *posp = '\\';
}

Not sure if this is a better approach than above answers.
