.SH NAME
wcstoimax, wcstoumax \- convert a wide-character string to an integer
type
.SH SYNOPSIS
.LP
\fB#include <stddef.h>
.br
#include <inttypes.h>
.br
.sp
intmax_t wcstoimax(const wchar_t *restrict\fP \fInptr\fP\fB,
.br
\ \ \ \ \ \ wchar_t **restrict\fP \fIendptr\fP\fB, int\fP \fIbase\fP\fB);
.br
uintmax_t wcstoumax(const wchar_t *restrict\fP \fInptr\fP\fB,
.br
\ \ \ \ \ \ wchar_t **restrict\fP \fIendptr\fP\fB, int\fP \fIbase\fP\fB);
.br
\fP
.SH DESCRIPTION
.LP
These functions shall be equivalent to the \fIwcstol\fP(), \fIwcstoll\fP(),
\fIwcstoul\fP(), and \fIwcstoull\fP() functions, respectively, except
that the initial portion of the wide string
shall be converted to \fBintmax_t\fP and \fBuintmax_t\fP representation,
respectively.
.SH RETURN VALUE
.LP
These functions shall return the converted value, if any.
.LP
If no conversion could be performed, zero shall be returned. If the
correct value is outside 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
\fIerrno\fP shall be set to [ERANGE].
.SH ERRORS
.LP
These functions shall fail if:
.TP 7
.B EINVAL
The value of \fIbase\fP is not supported.
.TP 7
.B ERANGE
The value to be returned is not representable.
.sp
.LP
These functions may fail if:
.TP 7
.B EINVAL
No conversion could be performed.
