NAME
cgGetNextProgram - iterate through programs in a context
SYNOPSIS
#include <Cg/cg.h> CGprogram cgGetNextProgram( CGprogram prog );PARAMETERS
- prog
Specifies the program.
DESCRIPTION
The programs within a context can be iterated over by using the cgGetNextProgram function. The following example code illustrates one way to do this:
CGprogram prog = cgGetFirstProgram( ctx ); while( prog ) { /* do something with prog */ prog = cgGetNextProgram( prog ) }Note that no specific order of traversal is defined by this mechanism. The only guarantee is that each program will be visited exactly once. No guarantees can be made if programs are generated or deleted during iteration.
RETURN VALUES
cgGetNextProgram returns the next program in the context's internal sequence of programs. Returns 0 when prog is the last program in the context.
ERRORS
CG_INVALID_PROGRAM_HANDLE_ERROR is generated if prog does not refer to a valid program.
