SCons C Pre-Processor module



Classes [hide private]
  FunctionEvaluator
Handles delayed evaluation of a #define function call.
  PreProcessor
The main workhorse class for handling C pre-processing.
  DumbPreProcessor
A preprocessor that ignores all #if/#elif/#else/#endif directives and just reports back *all* of the #include files (like the classic SCons scanner did).
Functions [hide private]
 
CPP_to_Python_Ops_Sub(m) source code
 
CPP_to_Python(s)
Converts a C pre-processor expression into an equivalent Python expression that can be evaluated.
