.TH POSIX_SPAWNATTR_GETSIGDEFAULT 3C "Jan 30, 2004"
.SH NAME
posix_spawnattr_getsigdefault, posix_spawnattr_setsigdefault \- get and set
spawn-sigdefault attribute of spawn attributes object
.SH SYNOPSIS
.LP
.nf
#include <signal.h>
#include <spawn.h>
\fBint\fR \fBposix_spawnattr_getsigdefault\fR(\fBconst posix_spawnattr_t *restrict\fR \fIattr\fR,
\fBsigset_t *restrict\fR \fIsigdefault\fR);
.fi
.LP
.nf
\fBint\fR \fBposix_spawnattr_setsigdefault\fR(\fBposix_spawnattr_t *restrict\fR \fIattr\fR,
\fBconst sigset_t *restrict\fR \fIsigdefault\fR);
.fi
.SH DESCRIPTION
.sp
.LP
The \fBposix_spawnattr_getsigdefault()\fR function obtains the value of the
\fIspawn-sigdefault\fR attribute from the attributes object referenced by
\fIattr\fR.
.sp
.LP
The \fBposix_spawnattr_setsigdefault()\fR function sets the
\fIspawn-sigdefault\fR attribute in an initialized attributes object referenced
by \fIattr\fR.
.sp
.LP
The \fIspawn-sigdefault\fR attribute represents the set of signals to be forced
to default signal handling in the new process image (if
\fBPOSIX_SPAWN_SETSIGDEF\fR is set in the \fIspawn-flags\fR attribute) by a
spawn operation. The default value of this attribute is an empty signal set.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, \fBposix_spawnattr_getsigdefault()\fR returns 0 and
stores the value of the \fIspawn-sigdefault\fR attribute of \fIattr\fR into the
object referenced by the \fIsigdefault\fR parameter. Otherwise, an error
number is returned to indicate the error.
.sp
.LP
Upon successful completion, \fBposix_spawnattr_setsigdefault()\fR returns 0.
Otherwise, an error number is returned to indicate the error.
.SH ERRORS
.sp
.LP
These functions may fail if:
.sp
.ne 2
.na
\fB\fBEINVAL\fR\fR
.ad
.RS 10n
The value specified by \fIattr\fR is invalid.

.LP
The \fBposix_spawnattr_setsigdefault()\fR function may fail if:
.sp
.ne 2
.na
\fB\fBEINVAL\fR\fR
.ad
