Use the -l c option to qcc to link against this library. This library is usually included automatically.
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().
For more information about spawn attributes, see the entry for posix_spawn().
