Module cpp

SCons C Pre-Processor module

Classes

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

CPP_to_Python_Ops_Sub(m)

CPP_to_Python(s)
Converts a C pre-processor expression into an equivalent Python expression that can be evaluated.
