# this exemple illustrates the use of the cparser/preprocessor #factorize functionnality:
|
|
|
|
|
# we write some code using standard headers, and the factorize call on CParser
|
|
|
|
|
# gives us back the macro/C definitions that we use in our code, so that we can
|
|
|
|
|
# get rid of the header
|
|
|
|
|
# Argument: C file to factorize, [path to visual studio installation]
|
|
|
|
|
# with a single argument, uses GCC standard headers
