strrstr3pub
Locate last occurrence of substring
Usage
#include <publib.h> char *strrstr(const char *str, const char *pat);
Overview
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.
Examples
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;
}
