ANSI_SYNOPSIS
|
||
|
|
#include <string.h>

TRAD_SYNOPSIS
|
||
|
|
#include <string.h>
|
||
|
|
char * strchrnul(<[string]>, <[c]>);

const char *<[string]>;
|
||
|
|
int <[c]>;
|

DESCRIPTION
|
||
|
|
This function finds the first occurence of <[c]> (converted to
|
||
|
|
a char) in the string pointed to by <[string]> (including the
|
||
|
|
terminating null character).
|
||
|
|
|
||
|
|
RETURNS
|
||
|
|
Returns a pointer to the located character, or a pointer
|
||
|
|
to the concluding null byte if <[c]> does not occur in <[string]>.
|
||
|
|
|
||
|
|
PORTABILITY
|
||
|
|
<<strchrnul>> is a GNU extension.
|
||
|
|
|
||
|
|
<<strchrnul>> requires no supporting OS subroutines. It uses
|
||
|
|
strchr() and strlen() from elsewhere in this library.
