Hi,
I am trying to define macros that will accept code blocks. This will be used to
create high level structures (like iterations, etc.). Ideally, I would like to
do something like (this is simplified example, actual code much more
application specific):
Foreach(var, low, high, block)
While should translate to:
For (int var=low ; var < high ; var ++) block
The challnge is the gcc pre processor does not accept blocks. It assume a comma
terminate a block. For example:
Foreach(foo, 1, 30, { int z=5, y=3, …}) will invoke the macro with 5 arguments:
(1) foo (2) 1, (3) 30, (4) { int z=5}, (5) y=3,
Is there a way to tell CPP that an argument that start with ‘{‘ should extend
until the matching ‘}’ ? Similar to the way ‘(‘ in macro arguments will extend
till matching ‘)’.
Thanks, yair.
