Destroy a synchronization object
#include <sys/neutrino.h> int SyncDestroy( sync_t* sync ); int SyncDestroy_r ( sync_t* sync );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The SyncDestroy() and SyncDestroy_r() kernel calls destroy a synchronization object previously allocated by a call to SyncTypeCreate(). You can destroy a locked mutex only if you're its owner. If the object is a condition variable with waiting threads, the call fails. Any attempt to use sync after it is destroyed fails.
These functions are identical except in the way they indicate errors. See the Returns section for details.
Blocking states
These calls don't block.
The only difference between these functions is the way they indicate errors:
