PRCallOnceType

Structure for tracking initialization.

Syntax

#include <prinit.h>

typedef struct PRCallOnceType {
  PRIntn initialized;
  PRInt32 inProgress;
  PRStatus status;
} PRCallOnceType;

Fields

The structure has these fields:

initialized: If not zero, the initialization process has been completed.
inProgress: If not zero, the initialization process is currently being executed. Calling threads that observe this status block until inProgress is zero.
status: An indication of the outcome of the initialization process.

Description

The client is responsible for initializing the PRCallOnceType structure to all zeros. This initialization must be accomplished before any threading issues exist.
