STRCHR(3) Linux Programmer's Manual STRCHR(3)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.
