#### NAME

> posix_spawnattr_getpgroup, posix_spawnattr_setpgroup - get and set the spawn-pgroup attribute of a spawn attributes object (ADVANCED REALTIME)

#### SYNOPSIS

> ``[SPN] #include <spawn.h>
> int posix_spawnattr_getpgroup(const posix_spawnattr_t *restrict` attr`,
> pid_t *restrict` pgroup`);
> int posix_spawnattr_setpgroup(posix_spawnattr_t *`attr`, pid_t` pgroup`);``
> `
> `

#### DESCRIPTION

> The posix_spawnattr_getpgroup() function shall obtain the value of the spawn-pgroup attribute from the attributes object referenced by attr.

> The posix_spawnattr_setpgroup() function shall set the spawn-pgroup attribute in an initialized attributes object referenced by attr.

> The spawn-pgroup attribute represents the process group to be joined by the new process image in a spawn operation (if POSIX_SPAWN_SETPGROUP is set in the spawn-flags attribute). The default value of this attribute shall be zero.

#### RETURN VALUE

> Upon successful completion, posix_spawnattr_getpgroup() shall return zero and store the value of the spawn-pgroup attribute of attr into the object referenced by the pgroup parameter; otherwise, an error number shall be returned to indicate the error.

> Upon successful completion, posix_spawnattr_setpgroup() shall return zero; otherwise, an error number shall be returned to indicate the error.

#### ERRORS

> These functions may fail if:

> [EINVAL]
>   The value specified by attr is invalid.

> The posix_spawnattr_setpgroup() function may fail if:

> [EINVAL]
>   The value of the attribute being set is not valid.
