Chapter 42 Error Handling Functions 29-1
29. ERROR HANDLING FUNCTIONS
The Error Handling functions allow the user to determine when a specific error should or should not occur.
In addition the current status of a device may be obtained.
29.1 AL_SetErrOnReInitRunning
Prototype C\C++
ERRNUM AL_SetErrOnReInitRunning(LHLD lhld, long lState);
Visual Basic for Windows
Function AL_SetErrOnReInitRunning(ByVal lhld As Long,
ByVal lState As Long) As Long
LHLD lhld handle of the LDSD
long lState specifies the re-initialization state
The AL_SetErrOnReInitRunning function sets the hardware re-initialization authorization of the LDSD.
Essentially this function affects whether the AL_InitDevice function is allowed to initialize a hardware
device while the device itself is in a running state.
Parameter Description
lhld Identifies the instance of the logical device subsystem.
lState
Specifies the re-initialization authorization state of the LDSD. The available
settings are defined in the ADLIB include file as follows:
• “ALLOW_REINIT” The device will first be stopped and then
reinitialized to the current settings.
• “DISALLOW_REINIT“ Reinitialization of the device will not be
allowed when the device is running and will
return an error.
Returns:
On success ERRNUM is set to 1, otherwise ERRNUM contains the last error code that occurred during the
call.
