46 .TH POSIX_SPAWNATTR_GETSCHEDPOLICY 3C "Jan 30, 2004"
48 posix_spawnattr_getschedpolicy, posix_spawnattr_setschedpolicy \- get and set
49 spawn-schedpolicy attribute of spawn attributes object
56 \fBint\fR \fBposix_spawnattr_getschedpolicy\fR(
57 \fBconst posix_spawnattr_t *restrict\fR \fIattr\fR,
58 \fBint *restrict\fR \fIschedpolicy\fR);
63 \fBint\fR \fBposix_spawnattr_setschedpolicy\fR(\fBposix_spawnattr_t *\fR\fIattr\fR,
64 \fBint\fR \fIschedpolicy\fR);
70 The \fBposix_spawnattr_getschedpolicy()\fR function obtains the value of the
71 \fIspawn-schedpolicy\fR attribute from the attributes object referenced by
75 The \fBposix_spawnattr_setschedpolicy()\fR function sets the
76 \fIspawn-schedpolicy\fR attribute in an initialized attributes object
77 referenced by \fIattr\fR.
80 The \fIspawn-schedpolicy\fR attribute represents the scheduling policy to be
81 assigned to the new process image in a spawn operation (if
82 \fBPOSIX_SPAWN_SETSCHEDULER\fR is set in the \fIspawn-flags\fR attribute). The
83 default value of this attribute is unspecified.
87 Upon successful completion, \fBposix_spawnattr_getschedpolicy()\fR returns 0
88 and stores the value of the \fIspawn-schedpolicy\fR attribute of \fIattr\fR
89 into the object referenced by the \fIschedpolicy\fR parameter. Otherwise, an
90 error number is returned to indicate the error.
93 Upon successful completion, \fBposix_spawnattr_setschedpolicy()\fR returns 0.
94 Otherwise, an error number is returned to indicate the error.
98 These functions may fail if:
105 The value specified by \fIattr\fR is invalid.
110 The \fBposix_spawnattr_setschedpolicy()\fR function may fail if:
117 The value of the attribute being set is not valid.
