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.
