24.2 AL_GetInputConfigList

Prototype C\C++

ERRNUM AL_GetInputConfigList(LHLD lhld, LPINPUTCONFIGLIST lpInputConfiglist);

Visual Basic for Windows

Function AL_GetInputConfigList(ByVal lhld As Long, lpInputConfiglist As

INPUTCONFIGLIST) As Long

LHLD lhld handle of the LDSD

LPINPUTCONFIGLIST lpInputConfiglist destination address of the user channel list structure

The AL_GetInputConfigList function retrieves to the current LDSD InputConfig list. The

INPUTCONFIG listing is comprised of a channel number and InputConfig type. The InputConfig list may

contain Channel/InputConfig settings that are not currently set in the channel listing itself. The

InputConfigID setting in the array can be obtained from the capability file.

Parameter Description

lhld Identifies the instance of the logical device subsystem.

lpInputConfiglist Specifies a 32 bit far pointer to a INPUTCONFIG information structure. This

structure has been predefined in the ADLIB include file and is defined as

follows:

typedef struct tagINPUTCONFIGLIST

{

long lType; /* 0 = Not Defined */

/* 1 = Use string list */

/* 2 = Use array of ints */

char achInputConfigList[MAX_INPUTCONFIG_STRLEN];

long lNumElements;

long alInputConfigList[MAX_INPUTCONFIG_LIST_ARRAYLEN];

}INPUTCONFIG;

typedef INPUTCONFIG FAR * LPINPUTCONFIGLIST;

Returns:

On success ERRNUM is set to 1 and the lpInputConfiglist structure is filled with the device's InputConfig

list settings, otherwise ERRNUM contains the last error code that occurred during the call and the

lpInputConfiglist structure may contain invalid information.
