Memory Allocation

You should use the UFO memory allocation mechanism to dynamically allocate and free memory. This will make use of the Softimage Compositor’s memory manager. The functions ufoMalloc, ufoRealloc, and ufoFree have the same functionality as the malloc, realloc and free system calls.

Order of UFO Process User Function Calls

UFO user functions are called as follows:

Softimage Compositor Initialization

    ufoProcessDefine

UFO Process Instance Copy

    ufoProcessCopyUserData

UFO Process Instance Destruction

    ufoProcessDeleteUserData

UFO Process Instance Saving and Loading

    ufoProcessWriteAsciiData
    ufoProcessReadAsciiData
    ufoProcessWriteBinaryData
    ufoProcessReadBinaryData
