## Public Member Functions

virtual csVertexAttrib | ResolveBufferDestination (const char *)
virtual int | ResolveTU (const char *)
| When the destination of a texture binding wasn't recognized, the FP is asked whether it can provide a TU number for it.

## Protected Types

enum | ProgramParamType
| Expected/accepted types for a program parameter. More...

## Protected Member Functions
