Find the last occurrence of a character in a string
#include <string.h>
const char* strrchr(const char* s,
int c );
- s
- The string that you want to search.
- c
- The character that you're looking for.

Use the -l c option to
qcc
to link against this library.
This library is usually included automatically.
The strrchr() function locates
the last occurrence of c (converted to a char)
in the string pointed
to by s.
The terminating null character is considered to be part of the string.
A pointer to the located character,
or a NULL pointer if the character doesn't occur in the string.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main( void )
{
printf( "%s\n", strrchr( "abcdeabcde", 'a' ) );
if( strrchr( "abcdeabcde", 'x' ) == NULL )
printf( "NULL\n" );
return EXIT_SUCCESS;
}
produces the output:
