posix_spawnattr_setrunmask()

Set the runmask attribute in a spawn attributes object

Synopsis:

#include <spawn.h>

int posix_spawnattr_setrunmask(
       posix_spawnattr_t *attrp,
       uint32_t runmask);

Arguments:

attrp: A pointer to the spawn attributes object that you want to modify.
runmask: The runmask that you want to use for the spawned processes.

Library:

libc

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

Description:

The posix_spawnattr_getrunmask() routine sets the value of the runmask attribute in the given spawn attributes object. You must have already initialized the spawn attributes object by calling posix_spawnattr_init().

This attribute is a bitmask of the processors that the spawned program can run on. Processor numbering starts at 0, with each processor corresponding to a bit in the runmask. For example, a runmask of 0x00000005 indicates that the spawned process is restricted to CPUs 0 and 2. For more information, see the Multicore Processing User's Guide.

This setting takes effect only if the POSIX_SPAWN_EXPLICIT_CPU flag is set; to set this flag, call posix_spawnattr_setxflags(). The default mask is 0xFFFFFFFFU, indicating that the spawned process can run on any processor.

To get the value of this attribute, call posix_spawnattr_getrunmask().

For more information about spawn attributes, see the entry for posix_spawn().

This function is a BlackBerry 10 OS extension.

Returns:

EOK: Success.
EINVAL: An argument was invalid.

Classification:

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

1. Choose your focus

This is the focus controller. Use this controller to choose your primary development approach (Cascades or Core).

By selecting a focus, you get to decide what content should be front and center on the site.
2. Download the tools

Before you start developing, you'll need to visit the Downloads tab. Here you'll find downloads for the BlackBerry 10 Native SDK, BlackBerry 10 Device Simulator, and some other useful tools.
3. Try the sample apps

Now featuring a filter control, the Sample apps tab allows you to search for samples by name or by feature.

Select either the Core or Cascades check boxes to display the samples relevant to your focus.
4. Educate yourself

The Documentation tab contains tons of examples, tutorials, and best practices to guide you along the path towards building an awesome app.

The documentation for your preferred focus always appears at the top of the left-hand navigation, but you can still access the rest of the documentation at the bottom.
5. Start developing

The Reference tab is where you'll find essential details about how to use our APIs.

You can use the left-hand navigation to choose how you would like to browse the reference: by module, by topic, or alphabetically. If you have an idea of what you are looking for, start typing it in the Filter box.
