const pVECTORCAMERA pCamera; |
/* pointer to a structure */ |
Sets the new camera settings.
Parameter |
Description |
pVector |
Pointer to a vector handle. |
pCamera |
Pointer to a VECTORCAMERA structure that contains the new camera settings. If this is NULL, the default camera settings will be used. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
