ost::Lockfile(3) Library Functions Manual ost::Lockfile(3) NAME
ost::Lockfile - This class is used to create a 'named' lock entity that can be used to control access to a resource between multiple processes. SYNOPSIS
#include <process.h> Public Member Functions Lockfile (const char *name) Create a lock under a known name. Lockfile () Create a new lock object that can be used to make locks. ~Lockfile () Destroy the current lock and release it. bool lock (const char *name) Lock a system-wide name for this process. void unlock (void) Release an acquired lock. bool isLocked (void) Flag if the current process has aqcuired a lock. Detailed Description This class is used to create a 'named' lock entity that can be used to control access to a resource between multiple processes. The posix implimentation uses a pidfile and the win32 version uses a globally visible mutex. Author: David Sugar dyfet@ostel.com System-wide named lock Constructor &; Destructor Documentation ost::Lockfile::Lockfile (const char *name) Create a lock under a known name. Parameters: name of system-wide lock to create. ost::Lockfile::Lockfile () Create a new lock object that can be used to make locks. ost::Lockfile::~Lockfile () [inline] Destroy the current lock and release it. Member Function Documentation bool ost::Lockfile::isLocked (void) Flag if the current process has aqcuired a lock. Returns: true if we have the lock. bool ost::Lockfile::lock (const char *name) Lock a system-wide name for this process. If the lock is successful, return true. If an existing lock was already acquired, release it first. Returns: true if lock successful. Parameters: name system-wide lock to use. void ost::Lockfile::unlock (void) Release an acquired lock.
