STRRSTR(3pub) C Programmer's Manual STRRSTR(3pub)

NAME

strrstr - 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; }
