strrstr()


Function
Scans a string for the last occurrence of a given substring.

Syntax
int strrstr(string s1, string s2[, int index]);

Returns
The strrstr function returns the integer offset of the first character of s2 in s1, or -1 if the substring does not occur in the string.

See also strstr, strrchr

If index is given, the search starts at that position. Negative values are counted from the end of the string.

Example

string s1 = "This is a string", s2 = "is a";
int pos = strrstr(s1, s2);
if (pos >= 0)
   printf("The substring starts at %d\n", pos);
else
   printf("The substring was not found\n");
