ERRNUM AL_SetErrOnReleaseRunning (LHLD lhld, long lState);

Visual Basic for Windows

Function AL_SetErrOnReleaseRunning(ByVal lhld As Long,

ByVal lState As Long) As Long

LHLD lhld handle of the LDSD

long lState specifies the release on running state

The AL_SetErrOnReleaseRunning function sets the hardware release on running authorization of the

LDSD. Essentially this function affects whether the AL_ReleaseDevice function is allowed to release 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 release on running authorization state of the LDSD. The available settings

are defined in the ADLIB include file as follows:

• “DISALLOW_RELEASE“ The device will first be stopped and then released.

• “ALLOW_RELEASE“ Release 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.

Supported Logical Device Subsystems:
