SYNOPSIS

This defines the callable interface to the TAU routines. These provide a C interface the TAU registers and functionality.

See also the inlined versions of these routines in TAU.ih.

Function Documentation

int TAU_aread (  TAU_request *  request  )

Perform an asynchronous read. This call should be matched with a TAU_await (). Returns: Status of the que operation, if 0, successfully queued Parameters: request  An un-initialized request structure

int TAU_await (  TAU_request *  request  )

Waits for the completion of the read request. Returns: Status Parameters: request  The request being waited on

void TAU_connect (  TAU_isr *  isr  )

Connects the specified routine as the TAU interrupt handler. Returns: The current interrupt service routine. The user should restore this routine when finished. NULL is returned on failure. Parameters: isr  The interrupt service routine to connect

void TAU_initialize (  int  sitv  )

Initializes the TAU facility. This is a one-time only initialization call. When finished with the facility, call TAU_shutdown ().

int TAU_qread (  TAU_request *  request  )

Ques a read of the temperature. Returns: Status, indicating the success or failure of queing the read Parameters: request  A previously initialized read request. One should use the macro TAU_REQUEST_INIT to initialize this structure. This routine calls back the completion routine buried in the request structure when the read is complete.

int TAU_read (  void   )

Issues a synchronous read request. Returns: If > 0, the temperature, else, error

int TAU_restore (  TAU_isr *  prvIsr  )

Restores the specified interrupt service routine as the current thermal exception handler prvIsr The interrupt service routine to restore. Returns: Status

void TAU_shutdown (  void   )

Restores the original VxWorks routine. This routine restores the original interrupt service handler

int TAU_sread (  TAU_request *  request  )

Issues a synchronous read request. Returns: Status
