posix_spawnattr_getxflags()

#include <spawn.h>

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

Since:

BlackBerry 10.0.0

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 BlackBerry 10 OS 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:

• POSIX_SPAWN_SETPGROUP
• POSIX_SPAWN_SETSIGMASK
• POSIX_SPAWN_SETSIGDEF
• POSIX_SPAWN_SETSCHEDULER
• POSIX_SPAWN_SETSCHEDPARAM
• POSIX_SPAWN_RESETIDS

BlackBerry 10 OS defines the following extended flags:

• POSIX_SPAWN_ALIGN_DEFAULT
• POSIX_SPAWN_ALIGN_FAULT
• POSIX_SPAWN_ALIGN_NOFAULT
• POSIX_SPAWN_ASLR_INVERT
• POSIX_SPAWN_CHECK_SCRIPT
• POSIX_SPAWN_DEBUG
• POSIX_SPAWN_EXEC
• POSIX_SPAWN_EXPLICIT_CPU
• POSIX_SPAWN_HOLD
• POSIX_SPAWN_NEWAPP
• POSIX_SPAWN_NOZOMBIE
• POSIX_SPAWN_PADDR64_SAFE
• POSIX_SPAWN_SEARCH_PATH
• POSIX_SPAWN_SETCRED
• POSIX_SPAWN_SETND
• POSIX_SPAWN_SETSID
• POSIX_SPAWN_SETSIGIGN
• POSIX_SPAWN_SETSTACKMAX
• POSIX_SPAWN_TCSETPGROUP

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().

Returns:

EOK

Success.

EINVAL

The value specified by attrp or flags_p is invalid.
