posix_spawnattr_getxflags()

Get the possible attribute flags that can be set when a process is spawned

Synopsis:

#include <posix_spawnattr.h>

int posix_spawnattr_getxflags(
       const posix_spawnattr_t *_Restrict attrp,
       uint32_t *_Restrict flags_p);

Arguments:

attrp
A spawn attribute object.
flags_p
QNX provides several extended attribute settings to extend the range of possible flags values using a unit32_t type for these extended flags. The flags are:

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 obtains the extended value of the spawn-flags attribute from the attributes object referenced by attrp.

POSIX specifies posix_spawnattr_setflags() and posix_spawnattr_getflags() routines for the setting of predefined flags using a flags parameter, which is defined as a short type.


Note: This function is a QNX Neutrino extension to posix_spawnattr_t().

Returns:

Upon successful completion, posix_spawnattr_getxflags() returns zero; otherwise, an error number is returned to indicate the error (errno is set).

Errors:

EINVAL
For any invalid parameter.
ENOMEM
The partition ID couldn't be added to the attributes object.
EOK
Success.

Classification:

QNX Neutrino

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