WCSTOIMAX(3P)			    POSIX Programmer's Manual			    WCSTOIMAX(3P)

PROLOG
       This  manual  page  is part of the POSIX Programmer's Manual.  The Linux implementation of
       this interface may differ (consult the corresponding Linux  manual  page  for  details  of
       Linux behavior), or the interface may not be implemented on Linux.

NAME
       wcstoimax, wcstoumax - convert a wide-character string to an integer type

SYNOPSIS
       #include <stddef.h>
       #include <inttypes.h>

       intmax_t wcstoimax(const wchar_t *restrict nptr,
	      wchar_t **restrict endptr, int base);
       uintmax_t wcstoumax(const wchar_t *restrict nptr,
	      wchar_t **restrict endptr, int base);

DESCRIPTION
       These  functions shall be equivalent to the wcstol(), wcstoll(), wcstoul(), and wcstoull()
       functions, respectively, except that the initial portion of the wide string shall be  con-
       verted to intmax_t and uintmax_t representation, respectively.

RETURN VALUE
       These functions shall return the converted value, if any.

       If  no conversion could be performed, zero shall be returned. If the correct value is out-
       side the range of representable values, {INTMAX_MAX}, {INTMAX_MIN}, or {UINTMAX_MAX} shall
       be  returned (according to the return type and sign of the value, if any), and errno shall
       be set to [ERANGE].

ERRORS
       These functions shall fail if:

       EINVAL The value of base is not supported.

       ERANGE The value to be returned is not representable.

       These functions may fail if:

       EINVAL No conversion could be performed.
