cgGetNextProgram(3)

NAME
cgGetNextProgram - iterate through programs in a context

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

PARAMETERS
The current program.

RETURN VALUES
Returns the next program in the context's internal sequence of programs.

Returns NULL when program is the last program in the context.

DESCRIPTION
The programs within a context can be iterated over by using cgGetNextProgram.

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.

EXAMPLES
  CGprogram program = cgGetFirstProgram( context );
  while( program )
  {
    /* do something with program */
    program = cgGetNextProgram( program )
  }

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

HISTORY
cgGetNextProgram was introduced in Cg 1.1.
