Use the -l c option to qcc to link against this library. This library is usually included automatically.
The posix_spawnattr_setflags() function stores the POSIX flags in the spawn attributes object pointed to by attrp, overwriting any previously saved POSIX flags. 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().
To set the extended flags, use posix_spawnattr_setxflags(). The posix_spawnattr_setflags() function doesn't affect any extended flags that you previously set in the spawn attributes object.
See posix_spawn().
