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         /* See feature_test_macros(7) */
       #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  multibyte
       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.

VERSIONS

       strchrnul() first appeared in glibc in version 2.1.1.

CONFORMING TO

       strchr() and strrchr() are in SVr4, 4.3BSD, C89, C99.  strchrnul() is a GNU extension.
