ANSI_SYNOPSIS
|
||
|
#include <wctype.h>
|
||
|
wctype_t wctype(const char *<[c]>);
|
||
|
|
||
|
TRAD_SYNOPSIS
|
||
|
#include <wctype.h>
|
||
|
wctype_t wctype(<[c]>)
|
||
|
const char * <[c]>;
|
||
|
|
||
|
|
||
|
DESCRIPTION
|
||
|
<<wctype>> is a function which takes a string <[c]> and gives back
|
||
|
the appropriate wctype_t type value associated with the string,
|
||
|
if one exists. The following values are guaranteed to be recognized:
|
||
|
"alnum", "alpha", "blank", "cntrl", "digit", "graph", "lower", "print",
|
||
|
"punct", "space", "upper", and "xdigit".
|
||
|
|
||
|
RETURNS
|
||
|
<<wctype>> returns 0 and sets <<errno>> to <<EINVAL>> if the
|
||
|
given name is invalid. Otherwise, it returns a valid non-zero wctype_t
|
||
|
value.
|
||
|
|
||
|
PORTABILITY
|
||
|
<<wctype>> is C99.
|
||
|
|
||
|
No supporting OS subroutines are required.
