Syntax

INT is_LockSeqBuf (HIDS hCam, INT nNum, char* pcMem)

Description

is_LockSeqBuf() locks write access to an image memory within a sequence. In the capturing process, locked image memories will be skipped in the sequence list of image memories to be used. This way, you can avoid that image data which are required for further processing will be overwritten by newly captured data. Full access to the image memory is still guaranteed. You can lock any number of image memories at the same time.

Using the is_UnlockSeqBuf() function, you can re-enable write access to the image memory.

Input Parameters

hCam

Camera handle

nNum

Number of the image memory to be locked (1...max) or IS_IGNORE_PARAMETER: The image memory will be identified by its starting address only.

pcMem

Starting address of the image memory to be locked

 

Achtung

nNum indicates the location in the sequence list, not the memory ID assigned using is_AllocImageMem().

Return Values

IS_SUCCESS

Function executed successfully

IS_NO_SUCCESS

General error message
