posix_spawnattr_setnode()

Set the remote node attribute in a spawn attributes object

Synopsis:

#include <spawn.h>

int posix_spawnattr_setnode( posix_spawnattr_t *attrp, 
                             uint32_t node);

Arguments:

attrp: A pointer to the spawn attributes object that you want to modify.
node: The identifier of the node that you want to spawn the process on.

Library:

libc

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

The posix_spawnattr_setnode() function sets the remote node attribute in the spawn attributes object referenced by attrp. You must have already initialized the spawn attributes object by calling posix_spawnattr_init().

This attribute specifies the descriptor of the node on which the child process is to be spawned if POSIX_SPAWN_SETND is set in the spawn flags; to set this flag, call posix_spawnattr_setxflags(). By default, the child is spawned on the node on which you call posix_spawn().

Use the netmgr_strtond() function to obtain a valid node identifier for a named remote node.

To retrieve the value of this attribute, call posix_spawnattr_getnode().

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