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
