INTRODUCTION

An update is available for Subsystem for UNIX-based Applications (SUA) on Windows Server 2003 R2-based computers. After you apply this update, when you call the pthread_testcancel function in a program, you can set a cancel state value that instructs the function to execute or return immediately.

This update introduces the following functions:
  • int setpthreadtestcancelstate(int testCancelState)

    The setpthreadtestcancelstate function sets the cancel state, depending on the testCancelState parameter. If the testCancelState parameter is set to 0, the pthread_testcancel function returns immediately without doing any operations. If the testCancelState parameter is set to 1, the pthread_testcancel function is executed.
  • int getpthreadtestcancelstate()

    The getpthreadtestcancelstate function displays the current cancel state.
