posix_spawnattr_getxflags()

Get the POSIX flags and the QNX Neutrino extended flags from a spawn attributes object

Synopsis:

#include <spawn.h>

int posix_spawnattr_getxflags(
       const posix_spawnattr_t *_Restrict attrp,
       uint32_t *_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_getxflags() function retrieves the POSIX flags and QNX Neutrino extended 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().

POSIX defines the following flags:

QNX Neutrino defines the following extended flags:

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().

Note: The posix_spawnattr_getxflags() function is a QNX Neutrino extension. POSIX specifies the posix_spawnattr_getflags() and posix_spawnattr_setflags() routines, which get and set only the POSIX flags.

Returns:

EOK
Success.
EINVAL
The value specified by attrp or flags_p is invalid.
