[in]	cameraMemoryArea	The camera memory area.

Returns

PEAK_STATUS_SUCCESS Operation was successful; no error occurred.

PEAK_STATUS_ACCESS_DENIED The camera memory area is not writeable. Check the access status via peak_CameraMemory_Area_GetAccessStatus. Check the list of currently usable camera memory areas via peak_CameraMemory_Area_GetList.

PEAK_STATUS_INVALID_PARAMETER cameraMemoryArea is an invalid camera memory area. Check peak_camera_memory_area.

PEAK_STATUS_INVALID_HANDLE hCam is an invalid camera handle.

PEAK_STATUS_NOT_INITIALIZED The library is not initialized.

PEAK_STATUS_ERROR An unexpected internal error occurred.

peak_CameraMemory_Area_Data_Read()

		peak_camera_memory_area	cameraMemoryArea,
		uint8_t *	data,
		size_t	dataSize
	)

Read from the specified camera memory area.

Reads the specified data from the specified camera memory area.

The data is read from the start of the camera memory area.

Parameters

[in]	hCam	The camera handle.
[in]	cameraMemoryArea	The camera memory area.
[in]	data	The buffer to receive the data to.
[in]	dataSize	The size of *data in bytes.

Returns

PEAK_STATUS_SUCCESS Operation was successful; no error occurred.

PEAK_STATUS_ACCESS_DENIED The camera memory area is not readable. Check the access status via peak_CameraMemory_Area_GetAccessStatus. Check the list of currently usable camera memory areas via peak_CameraMemory_Area_GetList.

PEAK_STATUS_OUT_OF_RANGE dataSize exceeds the size of the specified camera memory area. Check the size of the camera memory area via peak_CameraMemory_Area_Size_Get.

PEAK_STATUS_INVALID_PARAMETER cameraMemoryArea is an invalid camera memory area or dataSize is 0 or data is an invalid pointer. Check peak_camera_memory_area.

PEAK_STATUS_INVALID_HANDLE hCam is an invalid camera handle.

PEAK_STATUS_NOT_INITIALIZED The library is not initialized.

PEAK_STATUS_ERROR An unexpected internal error occurred.

peak_CameraMemory_Area_Data_Write()

peak_status peak_CameraMemory_Area_Data_Write	(	peak_camera_handle	hCam,
		peak_camera_memory_area	cameraMemoryArea,
		const uint8_t *	data,
		size_t	dataSize
	)

Write to a camera memory area.

Writes the specified data to the specified camera memory area.

The data is written to the start of the camera memory area. If dataSize is smaller than the capacity of the camera memory area, the remaining contents of the camera memory area are cleared.

Parameters

[in]	hCam	The camera handle.
[in]	cameraMemoryArea	The camera memory area.
[in]	data	The data to write.
[in]	dataSize	The size of *data in bytes.

Returns

PEAK_STATUS_SUCCESS Operation was successful; no error occurred.

PEAK_STATUS_ACCESS_DENIED The camera memory area is not writeable. Check the access status via peak_CameraMemory_Area_GetAccessStatus. Check the list of currently usable camera memory areas via peak_CameraMemory_Area_GetList.

PEAK_STATUS_OUT_OF_RANGE dataSize exceeds the size of the specified camera memory area. Check the size of the camera memory area via peak_CameraMemory_Area_Size_Get.

PEAK_STATUS_INVALID_PARAMETER cameraMemoryArea is an invalid camera memory area or dataSize is 0 or data is an invalid pointer. Check peak_camera_memory_area.

PEAK_STATUS_INVALID_HANDLE hCam is an invalid camera handle.

PEAK_STATUS_NOT_INITIALIZED The library is not initialized.

PEAK_STATUS_ERROR An unexpected internal error occurred.

peak_CameraMemory_Area_GetAccessStatus()

peak_access_status peak_CameraMemory_Area_GetAccessStatus	(	peak_camera_handle	hCam,
		peak_camera_memory_area	cameraMemoryArea
	)

Query the camera memory area access status.

Provides the current access status for the specified camera memory area.

This function implements the Access Status Query principle.

Parameters

[in]	hCam	The camera handle.
[in]	cameraMemoryArea	The camera memory area.

Returns

PEAK_ACCESS_READWRITE The camera memory area can be read from and written to.

PEAK_ACCESS_READONLY The camera memory area can be read from only.

PEAK_ACCESS_WRITEONLY The camera memory area can be written to only.

PEAK_ACCESS_GFA_LOCK The camera memory area is not accessible because the GFA write access is enabled.

PEAK_ACCESS_NONE The camera memory area is not accessible.

PEAK_ACCESS_NOT_SUPPORTED The camera memory area is not supported.

PEAK_ACCESS_INVALID The function failed. Call peak_Library_GetLastError to get the error code and description.

If the function indicates an error by returning PEAK_ACCESS_INVALID, these are the possible errors:

• PEAK_STATUS_INVALID_PARAMETER cameraMemoryArea is an invalid parameter set. Check peak_camera_memory_area.
• PEAK_STATUS_INVALID_HANDLE hCam is an invalid camera handle.
• PEAK_STATUS_NOT_INITIALIZED The library is not initialized.
• PEAK_STATUS_ERROR An unexpected internal error occurred.

peak_CameraMemory_Area_GetList()

peak_status peak_CameraMemory_Area_GetList	(	peak_camera_handle	hCam,
		peak_camera_memory_area *	cameraMemoryAreaList,
		size_t *	cameraMemoryAreaCount
	)

Get the list of currently usable camera memory areas.

Queries the list of currently selectable camera memory areas.

The list of usable camera memory areas may depend on the camera configuration and the camera status.

This function implements the Two Staged Data Query principle.

Parameters

[in]	hCam	The camera handle.
[out]	cameraMemoryAreaList	Pointer to a user allocated array buffer to receive the camera memory area list. If this parameter is NULL, cameraMemoryAreaCount will contain the current number of camera memory areas. The required size of cameraMemoryAreaList in bytes is cameraMemoryAreaCount x sizeof(peak_camera_memory_area).
[in,out]	cameraMemoryAreaCount	cameraMemoryAreaList equal NULL: out: minimal number of parameter sets cameraMemoryAreaList must be large enough to hold parameterSetList unequal NULL: in: number of camera memory areas cameraMemoryAreaList can hold out: number of camera memory areas filled by the function

Returns

PEAK_STATUS_SUCCESS Operation was successful; no error occurred.

PEAK_STATUS_BUFFER_TOO_SMALL cameraMemoryAreaList is not NULL and the value of *cameraMemoryAreaCount is too small to receive the expected amount of data.

PEAK_STATUS_ACCESS_DENIED The camera memory feature is not supported or the GFA write mode is enabled.

PEAK_STATUS_INVALID_PARAMETER cameraMemoryAreaCount is an invalid pointer.

PEAK_STATUS_INVALID_HANDLE hCam is an invalid camera handle.

PEAK_STATUS_NOT_INITIALIZED The library is not initialized.

PEAK_STATUS_ERROR An unexpected internal error occurred.

Note

Please consider that the camera memory area list might change between the size query call and the list query call.
This may be the case if the camera configuration or the camera status have changed in the time between the two function calls.

peak_CameraMemory_Area_Size_Get()

peak_status peak_CameraMemory_Area_Size_Get	(	peak_camera_handle	hCam,
		peak_camera_memory_area	cameraMemoryArea,
		size_t *	cameraMemoryAreaSize
	)

Get the size of a camera memory area.

Queries the size of the specified camera memory area.

Parameters

[in]	hCam	The camera handle.
[in]	cameraMemoryArea	The camera memory area.
[out]	cameraMemoryAreaSize	The size of the camera memory area in bytes.

Returns

PEAK_STATUS_SUCCESS Operation was successful; no error occurred.

PEAK_STATUS_ACCESS_DENIED The camera memory area is not accessible. Check the access status via peak_CameraMemory_Area_GetAccessStatus. Check the list of currently usable camera memory areas via peak_CameraMemory_Area_GetList.

PEAK_STATUS_INVALID_PARAMETER cameraMemoryArea is an invalid camera memory area or size is an invalid pointer. Check peak_camera_memory_area.

PEAK_STATUS_INVALID_HANDLE hCam is an invalid camera handle.

PEAK_STATUS_NOT_INITIALIZED The library is not initialized.

PEAK_STATUS_ERROR An unexpected internal error occurred.
