daqProcessError
DLL Function daqProcessError(DaqHandleT handle, DaqError errCode);
C daqProcessError(DaqHandleT handle, DaqError errCode);
Visual BASIC VBdaqProcessError&(ByVal handle&, ByVal errCode&)
Delphi daqProcessError(handle:DaqHandleT; errCode:DaqError)
Parameters
handle Handle to the device for which the specified error is to be processed.
errCode Specifies the device error code to process
Returns Refer to API Error Codes on page 11-39
See Also daqSetDefaultErrorHandler, daqGetLastError, daqDefaultErrorHandler
Program References None
Used With All devices
daqProcessError allows an application to initiate an error for processing by the driver. This
command can be used when it is desirable for the application to initiate processing for a device-
defined error.
daqSetDefaultErrorHandler
DLL Function daqSetDefaultErrorHandler(DaqErrorHandlerFPT handler);
C daqSetDefaultErrorHandler(DaqErrorHandlerFPT handler);
Visual BASIC VBdaqSetDefaultErrorHandler&(ByVal handler&)
Delphi daqSetDefaultErrorHandler(handler:DaqErrorHandlerFPT)
Parameters
handler Pointer to a user-defined error handler function.
Returns DerrNoError - No error (also, refer to API Error Codes on page 11-39)
See Also daqDefaultErrorHandler, daqGetLastError, daqProcessError, daqSetErrorHandler
Program References ERREX.PAS (Delphi)
Used With All devices
daqSetDefaultErrorHandler allows you to set the driver to use the default error handler
specified for all devices.
daqSetErrorHandler
DLL Function daqSetErrorHandler(DaqHandleT handle, DaqErrorHandlerFPT handler);
C daqSetErrorHandler(DaqHandleT handle, DaqErrorHandlerFPT handler);
Visual BASIC VBdaqSetErrorHandler&(ByVal handle&, ByVal handler&)
Delphi daqSetErrorHandler(handle:DaqHandleT; handler:DaqErrorHandlerFPT)
Parameters
handle Handle to the device to which to attach the specified error handler
handler Pointer to a user defined error handler function.
Returns DerrNoError - No error (also, refer to API Error Codes on page 11-39)
See Also daqSetDefaultErrorHandler, daqDefaultErrorHandler, daqGetLastError,
daqProcessError
Program References ADCEX1.C, DYN32ENH.C, DAQEX.FRM (VB), ERREX.PAS (Delphi)
Used With All devices
daqSetErrorHandler specifies the routine to call when an error occurs in any command. The
default routine displays a message and then terminates the program. If this is not desirable, use this
command to specify your own routine to be called when errors occur. If you want no action to occur
when a command error is detected, use this command with a null (0) parameter. The default error
routine is daqDefaultHandler.
