posix_spawnattr_getpgroup()

Get the spawn-pgroup attribute of a spawn attributes object

Synopsis:

#include <posix_spawnattr.h>

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

Arguments:

attrp
A spawn file attribute object.
pid_p
The child process's group if you specify POSIX_SPAWN_SETGROUP in the flags member.

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 spawn-pgroup attribute from the attributes object referenced by attrp.

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.

Returns:

Upon successful completion, posix_spawnattr_getpgroup() returns zero and stores the value of the spawn pid_p attribute of attrp into the object referenced by the pid_p parameter; otherwise, an error number is returned to indicate the error (errno is set).

Errors:

EINVAL
For any invalid parameter, or the value specified by attrp is invalid.
EOK
Success.

Classification:

POSIX 1003.1 RTS

Safety:
Cancellation point No
Interrupt handler Yes
Signal handler Yes
Thread Yes
