.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.
