NAME

strchr, strrchr, strchrnul - locate character in string  

SYNOPSIS

#include <string.h>

char *strchr(const char *s, int c);

char *strrchr(const char *s, int c);

#define _GNU_SOURCE
#include <string.h>

char *strchrnul(const char *s, int c);
 

DESCRIPTION

The strchr() function returns a pointer to the first occurrence of the character c in the string s.

The strrchr() function returns a pointer to the last occurrence of the character c in the string s.

The strchrnul() function is like strchr() except that if c is not found in s, then it returns a pointer to the null byte at the end of s, rather than NULL.

Here "character" means "byte"; these functions do not work with wide or multi-byte characters.  

RETURN VALUE

The strchr() and strrchr() functions return a pointer to the matched character or NULL if the character is not found.

The strchrnul() function returns a pointer to the matched character, or a pointer to the null byte at the end of s (i.e., s+strlen(s)) if the character is not found.
