Blocks the calling thread until a specified thread terminates.
#include <prthread.h> PRStatus PR_JoinThread(PRThread *thread);
PR_JoinThread has the following parameter:
threadThe function returns one of the following values:
PR_SUCCESSPR_FAILURE.PR_JoinThread is used to synchronize the termination of a thread. The function is synchronous in that it blocks the calling thread until the target thread is in a joinable state. PR_JoinThread returns to the caller only after the target thread returns from its root function.
PR_JoinThread must not be called until after PR_CreateThread has returned. If PR_JoinThread is not called on the same thread as PR_CreateThread, then it is the caller's responsibility to ensure that PR_CreateThread has completed.
Several threads cannot wait for the same thread to complete. One of the calling threads operates successfully, and the others terminate with the error PR_FAILURE.
The calling thread is not blocked if the target thread has already terminated.
PR_JoinThread is interruptable.
