The nCommand input parameter is used to select the function mode. The pParam input parameter depends on the selected function mode. If you select functions for setting or returning a value, pParam contains a pointer to a variable of the UINT type. The size of the memory area to which pParam refers is specified in the nSizeOfParam input parameter.Input parameters
hCam |
Camera handle |
pParam |
Pointer to a function parameter, whose function depends on nCommand. |
nSizeOfParam |
