.SH DESCRIPTION
|
||
|
.LP
|
||
|
The \fIposix_spawnattr_getsigmask\fP() function shall obtain the value
|
||
|
of the \fIspawn-sigmask\fP attribute from the
|
||
|
attributes object referenced by \fIattr\fP.
|
||
|
.LP
|
||
|
The \fIposix_spawnattr_setsigmask\fP() function shall set the \fIspawn-sigmask\fP
|
||
|
attribute in an initialized attributes
|
||
|
object referenced by \fIattr\fP.
|
||
|
.LP
|
||
|
The \fIspawn-sigmask\fP attribute represents the signal mask in effect
|
||
|
in the new process image of a spawn operation (if
|
||
|
POSIX_SPAWN_SETSIGMASK is set in the \fIspawn-flags\fP attribute).
|
||
|
The default value of this attribute is unspecified.
|
||
|
.SH RETURN VALUE
|
||
|
.LP
|
||
|
Upon successful completion, \fIposix_spawnattr_getsigmask\fP() shall
|
||
|
return zero and store the value of the
|
||
|
\fIspawn-sigmask\fP attribute of \fIattr\fP into the object referenced
|
||
|
by the \fIsigmask\fP parameter; otherwise, an error
|
||
|
number shall be returned to indicate the error.
|
||
|
.LP
|
||
|
Upon successful completion, \fIposix_spawnattr_setsigmask\fP() shall
|
||
|
return zero; otherwise, an error number shall be returned
|
||
|
to indicate the error.
|
||
|
