cgCompileProgram(3)

NAME
cgCompileProgram - compile a program object

SYNOPSIS
  #include <Cg/cg.h>
  void cgCompileProgram( CGprogram program );

PARAMETERS
The program object to compile.

RETURN VALUES
None.

DESCRIPTION
cgCompileProgram compiles the specified Cg program for its target profile. A program must be compiled before it can be loaded (by the API-specific part of the runtime). It must also be compiled before its parameters can be inspected.

Certain actions invalidate a compiled program and the current value of all of its parameters. If one of these actions is performed, the program must be recompiled before it can be used. A program is invalidated if the program source is modified, if the compile arguments are modified, or if the entry point is changed.

If one of the parameter bindings for a program is changed, that action invalidates the compiled program, but does not invalidate the current value of the program's parameters.

EXAMPLES
  if(!cgIsProgramCompiled(program))
   cgCompileProgram(program);

ASSOCIATED GETS
cgGetProgramString with pname CG_COMPILED_PROGRAM.

ERRORS
CG_INVALID_PROGRAM_HANDLE_ERROR is generated if program is not a valid program handle.

CG_COMPILER_ERROR is generated if compilation fails.

HISTORY
cgCompileProgram was introduced in Cg 1.1.
