Description:
The posix_spawnattr_getflags() function retrieves the POSIX flags from the spawn attributes object pointed to by attrp, and stores them in the object pointed to by flags_p. You must have already initialized the spawn attributes object by calling posix_spawnattr_init() .
These flags indicate which process attributes you want to change in the new process image when you invoke posix_spawn() or posix_spawnp(). For detailed information about the flags, see the entry for posix_spawn() .
