Get the "default signals" attribute of a spawn attributes object
#include <spawn.h> int posix_spawnattr_getsigdefault( const posix_spawnattr_t *_Restrict attrp, sigset_t *_Restrict sigset_p);
- A pointer to the spawn attributes object that you want to query.
- A pointer to a location where the routine can store the set of signals that are to be handled as per the default behavior.
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The posix_spawnattr_getsigdefault() function obtains the value of the "default signals" attribute from the attributes object referenced by attrp, and stores it in the signal set pointed to by sigset_p. 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 set the value of this attribute, call posix_spawnattr_setsigdefault() .
For more information about spawn attributes, see the entry for posix_spawn() .
- An argument was invalid.
