The type of an NSPR thread, specified as a parameter to PR_CreateThread
.
Syntax
#include <prthread.h> typedef enum PRThreadType { PR_USER_THREAD, PR_SYSTEM_THREAD } PRThreadType;
Enumerators
PR_USER_THREAD
PR_Cleanup
blocks until the last thread of typePR_USER_THREAD
terminates.PR_SYSTEM_THREAD
- NSPR ignores threads of type
PR_SYSTEM_THREAD
when determining when a call toPR_Cleanup
should return.
Description
Threads can be either user threads or system threads. NSPR allows the client to synchronize the termination of all user threads and ignores those created as system threads. This arrangement implies that a system thread should not have volatile data that needs to be safely stored away. The applicability of system threads is somewhat dubious; therefore, they should be used with caution.
