posix_spawnattr_getpgroup()

Get the process group attribute of a spawn attributes object

Synopsis:

#include <spawn.h>

int posix_spawnattr_getpgroup(
       const posix_spawnattr_t *_Restrict attrp,
       pid_t *_Restrict pid_p);

Since:

BlackBerry 10.0.0

Arguments:

attrp
A pointer to the spawn attributes object that you want to query.
pid_p
A pointer to a location where the function can store the group ID.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The posix_spawnattr_getpgroup() function gets the value of the process group attribute from the attributes object pointed to by attrp, and stores it in the object pointed to by pid_p. You must have already initialized the spawn attributes object by calling posix_spawnattr_init().

This 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; to set this flag, call the POSIX function posix_spawnattr_setflags(), or the BlackBerry 10 OS function posix_spawnattr_setxflags(). The default value of the process group attribute is zero.

You can use posix_spawnattr_setpgroup(). to set it.

For more information about spawn attributes, see the entry for posix_spawn().

Returns:

EOK
Success
EINVAL
The value specified by attrp or pid_p was invalid.

Classification:

POSIX 1003.1 SPN
