Synopsis:

       posix_spawnattr_t *_Restrict attrp,
       const sigset_t *_Restrict sigset_p);

Arguments:

Description:

The posix_spawnattr_getsigignore() routine sets the “ignored signals” attribute in the given spawn attributes object. You must have already initialized the spawn attributes object by calling posix_spawnattr_init().

This attribute specifies the set of signals that should be ignored by the spawned process. You must have already initialized the spawn attributes object by calling posix_spawnattr_init(). This setting takes only effect if the POSIX_SPAWN_SETSIGIGN flag is set in the spawn attributes; to set this flag, call posix_spawnattr_setxflags().

To get the value of this attribute, call posix_spawnattr_getsigignore().
