NAME

       strchr, strrchr - locate character in string

SYNOPSIS

       #include <string.h>

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

       char *strrchr(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.

       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.

CONFORMING TO

       SVID 3, POSIX, BSD 4.3, ISO 9899

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 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.
