Set a thread-specific data value
#include <pthread.h> int pthread_setspecific( pthread_key_t key, const void* value );
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The pthread_setspecific() function binds the thread specific data value value with the thread specific data key key.
You can call this function from within a thread-specific data destructor function.
|You must call this function with a key that you got from pthread_key_create(). You can't use a key after destroying it with pthread_key_delete().|
POSIX 1003.1 THR
Calling pthread_setspecific() with a non-NULL value may result in lost storage or infinite loops unless value was returned by pthread_key_create().
