posix_spawnattr_getflags()

Get the POSIX flags from a spawn attributes object

Synopsis:

#include <spawn.h>

int posix_spawnattr_getflags(
       const posix_spawnattr_t *_Restrict attrp,
       short *_Restrict flags_p);

Arguments:

attrp

A pointer to the spawn attributes object that you want to query.

flags_p

A pointer to a location where the function can store the flags.

Library:

libc

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

Description:

The posix_spawnattr_getflags() function retrieves the POSIX flags from the spawn attributes object pointed to by attrp, and stores them in the object pointed to by flags_p. You must have already initialized the spawn attributes object by calling posix_spawnattr_init().

These flags indicate which process attributes you want to change in the new process image when you invoke posix_spawn() or posix_spawnp(). For detailed information about the flags, see the entry for posix_spawn().

---

This function doesn't get the extended flags that QNX Neutrino defines: POSIX_SPAWN_SETND POSIX_SPAWN_SETSIGIGN POSIX_SPAWN_SETSPART POSIX_SPAWN_EXPLICIT_CPU POSIX_SPAWN_SETCRED POSIX_SPAWN_SETSTACKMAX POSIX_SPAWN_NOZOMBIE POSIX_SPAWN_HOLD POSIX_SPAWN_ALIGN_DEFAULT POSIX_SPAWN_ALIGN_FAULT POSIX_SPAWN_ALIGN_NOFAULT To get the extended flags, use posix_spawnattr_getxflags().

Returns:

EOK

Success.

EINVAL

The value specified by attrp or flags_p is invalid.

Classification:

POSIX 1003.1 SPN
