Description:

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 BlackBerry 10 OS function posix_spawnattr_setxflags() .

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

Success.

An argument was invalid.
