strrstr(3) locate last occurrence of substring

SYNOPSIS


#include <publib.h>
char *strrstr(const char *str, const char *pat);

DESCRIPTION

strrstr finds the last occurrence of the string pat in the string str. The terminating '\0' characters are not compared.

RETURN VALUE

strrstr returns a pointer to the first character of the substring, or NULL if the substring is not found.

EXAMPLE

To print out everything on each line starting with the last occurrence of "/* " on each line, you might use the following code:

#include <stdio.h>
#include <publib.h>
int main(void) {
        char *p, line[512];
        while (fgets(line, sizeof(line), stdin) != NULL) {
                p = strrstr(line, "/* ");
                if (p != NULL)
                        printf("%s", p);
        }
        return 0;
}
