NAME

strrstr - locate last occurence of substring

SYNOPSIS

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

 

DESCRIPTION

strrstr finds the last occurence 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 occurence 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;
 }
