POSIX_SPAWNATTR_GETPGROUP(3C) Standard C Library Functions POSIX_SPAWNATTR_GETPGROUP(3C)

posix_spawnattr_getpgroup, posix_spawnattr_setpgroup - get and set spawn-pgroup attribute of spawn attributes object

#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);

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

The posix_spawnattr_setpgroup() function sets 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 is zero.

Upon successful completion, posix_spawnattr_getpgroup() returns 0 and stores the value of the spawn-pgroup attribute of attr into the object referenced by the pgroup parameter. Otherwise, an error number is returned to indicate the error.

Upon successful completion, posix_spawnattr_setpgroup() returns 0. Otherwise, an error number is returned to indicate the error.

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.
