.SH NAME
strtoimax, strtoumax \- convert string to integer type
.SH SYNOPSIS
.LP
\fB#include <inttypes.h>
.br
.sp
intmax_t strtoimax(const char *restrict\fP \fInptr\fP\fB, char **restrict\fP
\fIendptr\fP\fB,
.br
\ \ \ \ \ \  int\fP \fIbase\fP\fB);
.br
uintmax_t strtoumax(const char *restrict\fP \fInptr\fP\fB, char **restrict\fP
\fIendptr\fP\fB,
.br
\ \ \ \ \ \  int\fP \fIbase\fP\fB);

.SH DESCRIPTION
.LP
These functions shall be equivalent to the \fIstrtol\fP(), \fIstrtoll\fP(),
\fIstrtoul\fP(), and \fIstrtoull\fP() functions, except that the initial
portion of the 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.
.LP
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 ERANGE
The value to be returned is not representable.
.sp
.LP
These functions may fail if:
.TP 7
.B EINVAL
The value of \fIbase\fP is not supported.
