Hi all
I came from a different language where you could have a macro like this:
mac_func1 macro &a, &b
some definitions...
which when you do
rc = mac_func1 parm1, parm2
will translate to
rc = func1 (1, parm1, parm2)
-------
in C I can do
#define mac_func1 (parm1, parm2) func1 (1, parm1, parm2)
however, if you do
rc = mac_func1 (myparm1, myparm2)
The compiler will yell about parm1 and parm2 not defined
Is there a way in C to virtualize the signature?
Thanks all

Remove the space before the macro's parameter list.
Usually it is recommended to post a small program that we can compile and test before answering your questions.
If you are compiling for a 32 or 64 bit O/S such as Windows or Linux, it is usually recommended to use normal functions rather than "macro functions". You really don't gain any noticeable efficiency over a normal function.
Macro functions are more error-prone! No type checking! Possible side effects. Possible code bloat. etc...
I no longer use them, or inline functions as well. Current compilers such as gcc or clang will do better optimizations, than you can get using macro functions.
Thank you all
Indeed I've left a space which was wrong
I will take the advice and will not use macro function as I realized that this could lead to errors as stated.
