NAME

strchrnul - string search character or NUL

LIBRARY

Standard C library (libc,~-lc)

SYNOPSIS

#define _GNU_SOURCE  /* See feature_test_macros(7) */
#include <string.h>
char *strchrnul(const char *s, int c);

DESCRIPTION

The strchrnul() function is like strchr(3) except that if c is not found in s, then it returns a pointer to the null byte at the end of s. It is equivalent to both of the following expressions: strchr(s, c) ?: strnul(s) s + strcspn(s, (char [2]){c, [aq][rs]0[aq]})

RETURN VALUE

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