.TH POSIX_SPAWNATTR_GETFLAGS 3C "Sep 25, 2008"
.SH NAME
posix_spawnattr_getflags, posix_spawnattr_setflags \- get and set spawn-flags
attribute of spawn attributes object
.SH SYNOPSIS
.LP
.nf
#include <spawn.h>
\fBint\fR \fBposix_spawnattr_getflags\fR(\fBconst posix_spawnattr_t *restrict\fR \fIattr\fR,
\fBshort *restrict\fR \fIflags\fR);
.fi
.LP
.nf
\fBint\fR \fBposix_spawnattr_setflags\fR(\fBposix_spawnattr_t *\fR \fIattr\fR, \fBshort\fR \fIflags\fR);
.fi
.SH DESCRIPTION
.sp
.LP
The \fBposix_spawnattr_getflags()\fR function obtains the value of the
\fIspawn-flags\fR attribute from the attributes object referenced by
\fIattr\fR.
.sp
.LP
The \fBposix_spawnattr_setflags()\fR function sets the \fIspawn-flags\fR
attribute in an initialized attributes object referenced by \fIattr\fR.
.sp
.LP
The \fIspawn-flags\fR attribute is used to indicate which process attributes
are to be changed in the new process image when invoking \fBposix_spawn\fR(3C)
or \fBposix_spawnp\fR(3C). It is the bitwise inclusive-OR of zero or more of
the following flags:
.br
.in +2
\fBPOSIX_SPAWN_RESETIDS\fR
.in -2
.br
.in +2
\fBPOSIX_SPAWN_SETPGROUP\fR
.in -2
.br

\fBPOSIX_SPAWN_SETSIGDEF\fR
.in -2
.br
.in +2
\fBPOSIX_SPAWN_SETSIGMASK\fR
.in -2
.br
.in +2
\fBPOSIX_SPAWN_SETSCHEDPARAM\fR
.in -2

\fBPOSIX_SPAWN_SETSCHEDULER\fR
.in -2

\fBPOSIX_SPAWN_NOSIGCHLD_NP\fR
.in -2
.br
.in +2
\fBPOSIX_SPAWN_WAITPID_NP\fR
.in -2
.br
.in +2
\fBPOSIX_SPAWN_NOEXECERR_NP\fR
.in -2
.sp
.LP
These flags are defined in \fB<spawn.h>\fR. The default value of this attribute
is as if no flags were set.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, \fBposix_spawnattr_getflags()\fR returns 0 and
stores the value of the spawn-flags attribute of attr into the object
referenced by the flags parameter. Otherwise, an error number is returned to
indicate the error.
.sp
.LP
Upon successful completion, \fBposix_spawnattr_setflags()\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.
