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;
}
