Writes output from the L_CompressBuffer function.
#include "l_bitmap.h"
L_INT pEXT_CALLBACK YourFunction (pBitmap, pBuffer, uBytes, pUserData)
Pointer to the bitmap handle that contains the image information.
Pointer to the caller's output buffer containing compressed data.
The number of bytes in the buffer.
A void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function. (This is the same pointer that you pass in the pUserData parameter of the calling function.)
Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
For an example, refer to L_StartCompressBuffer.
