[edit] Return value

Pointer to the found character in str, or a null pointer if no such character is found.

#include <iostream>
#include <cstring>
int main()
  const char *str = "Try not. Do, or do not. There is no try.";
  char target = 'T';
  const char *result = str;
  while ((result = std::strchr(result, target)) != NULL) {
    std::cout << "Found '" << target
              << "' starting at '" << result << "'\n";
    // Increment result, otherwise we'll find target at the same location


Found 'T' starting at 'Try not. Do, or do not. There is no try.'
Found 'T' starting at 'There is no try.'
