27.17 AL_SetAutoInitBuffers
Prototype C\C++
ERRNUM AL_SetAutoInitBuffers(LHLD lhld, long lState)
Visual Basic for Windows
Function AL_ SetAutoInitBuffers(ByVal lhld As Long, ByVal lState As long) As Long
LHLD lhld handle of the LDSD
long lState
desired state of the LDSD AutoInitBuffer flag
The AL_SetAutoInitBuffers function sets the LDSD buffer’s auto initialization authorization. Essentially
this function affects whether the AL_StartDevice function is allowed to auto initialize all LDSD buffers.
This is most useful when a AL_SINGLE_CYCLE operation has completed operation and another
acquisition is desired using the same LDSD buffers.
Parameter Description
lhld Identifies the instance of the logical device subsystem.
lState
Specifies the desired AutoInitBuffers authorization state of the LDSD. The available
settings are defined in the ADLIB include file as follows:
• YES The buffers will be auto initialized on AL_InitDevice calls.
• NO The buffers will NOT be auto initialized on AL_InitDevice calls.
Returns:
On success ERRNUM is set to 1, otherwise ERRNUM contains the last error code that occurred during the
call.
