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_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
  • POSIX_SPAWN_ASLR_INVERT

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
