The posix_spawnattr_getschedpolicy() function shall obtain the value of
the spawn-schedpolicy attribute from the attributes object referenced
The posix_spawnattr_setschedpolicy() function shall set the
spawn-schedpolicy attribute in an initialized attributes object
referenced by attr.
The spawn-schedpolicy attribute represents the scheduling policy to be
assigned to the new process image in a spawn operation (if
POSIX_SPAWN_SETSCHEDULER is set in the spawn-flags attribute). The
default value of this attribute is unspecified.
Upon successful completion, posix_spawnattr_getschedpolicy() shall return
zero and store the value of the spawn-schedpolicy attribute of
attr into the object referenced by the schedpolicy parameter;
otherwise, an error number shall be returned to indicate the error.
Upon successful completion, posix_spawnattr_setschedpolicy() shall return
zero; otherwise, an error number shall be returned to indicate the error.
