This chapter describes the NSPR API for versioning, process initialization, and shutdown of NSPR.

Initialization and Cleanup

NSPR detects whether the library has been initialized and performs implicit initialization if it hasn't. Implicit initialization should suffice unless a program has specific sequencing requirements or needs to characterize the primordial thread. Explicit initialization is rarely necessary.

Implicit initialization assumes that the initiator is the primordial thread and that the thread is a user thread of normal priority.

Module Initialization

Initialization can be tricky in a threaded environment, especially initialization that must happen exactly once. PR_CallOnce ensures that such initialization code is called only once. This facility is recommended in situations where complicated global initialization is required.
