Open All Cards

Description

Locates and opens all installed Pickering cards. Once cards have been opened, other functions may then be used to access cards numbered 1 thru the value returned.

If cards have already been opened by the calling program, they are first closed - as though by PIPLX_CloseCards - and then re-opened.

If cards are currently opened by some other program they cannot be accessed and the function returns zero.

Prototype

DWORD PIPLX_OpenCards(SESSION session);

Parameters:

Session - The session variable obtained from the PICMLX_Connect call

Returns:

The number of Pickering cards located and opened.

Note

When multiple Pickering cards are installed, the assignment of card numbers depends upon their relative physical locations in the system (or more accurately, on the order in which they are detected by the computer's operating system at boot time).
