STRCHR(3)                  Library Functions Manual                  STRCHR(3)

NAME
     strchr, strchrnul - locate character in string

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <string.h>

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

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

DESCRIPTION
     The strchr() and strchrnul() functions locate the first occurrence of c
     in the string pointed to by s.  The terminating NUL character is
     considered part of the string.  If c is `\0', strchr() and strchrnul()
     locate the terminating `\0'.

RETURN VALUES
     The function strchr() returns a pointer to the located character, or NULL
     if the character does not appear in the string.  The function strchrnul()
     returns a pointer to the located character, or a pointer to the NUL
     terminating character of the string if the character does not appear in
     the string.

EXAMPLES
     After the following call to strchr(), p will point to the string "oobar":

           char *p;
           char *s = "foobar";

           p = strchr(s, 'o');
