Use the -l c option to qcc to link against this library. This library is usually included automatically.
The posix_spawnattr_destroy() function destroys a spawn attributes object. You can reinitialize a destroyed attrp attributes object by using posix_spawnattr_init(); the results of referencing the object after you've destroyed it are undefined.
A spawn attributes object is an opaque object of type posix_spawnattr_t (defined in <spawn.h>), and it specifies the inheritance of process attributes across a spawn operation.
The resulting spawn attributes object (possibly modified by setting individual attribute values), is used to modify the behavior of posix_spawn() or posix_spawnp(). Changes that you make to the spawn attributes object don't affect any processes that you've already spawned.
