Get the remote node attribute from a spawn attributes object
#include <spawn.h> int posix_spawnattr_getnode( const posix_spawnattr_t *_Restrict attrp, uint32_t *_Restrict node_p);
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The posix_spawnattr_getnode() function retrieves the remote node attribute from the spawn attributes object referenced by attrp, and stores it in the object pointed to by node_p. 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().
To set the value of this attribute, call posix_spawnattr_setnode().
For more information about spawn attributes, see the entry for posix_spawn().
