Set the “default signals” attribute of a spawn attributes object
#include <spawn.h>
int posix_spawnattr_setsigdefault(
posix_spawnattr_t *_Restrict attrp,
const sigset_t *_Restrict sigset_p);

Use the -l c option to qcc to link against this library. This library is usually included automatically.
The posix_spawnattr_setsigdefault() function sets the “default signals” attribute in the attributes object referenced by attrp. You must have already initialized the spawn attributes object by calling posix_spawnattr_init().
This attribute represents the set of signals that will use the default signal handling in the new process image created by a spawn operation if POSIX_SPAWN_SETSIGDEF is set in the spawn-flags attribute; to set this flag, call the POSIX function posix_spawnattr_setflags(), or the QNX Neutrino function posix_spawnattr_setxflags().
To retrieve the current value of this attribute, call posix_spawnattr_getsigdefault().
For more information about spawn attributes, see the entry for posix_spawn().
