- Subject: using same macro arg as both: var and "var"?
Hi all,
I would like to define a macro with a single arg which
shall be used in both ways: The quoted and unquoted way:
#define macro1(a) void func##a(){ printf(a); }
Either way, of course, I get an error:
macro1(x); /* error: 'x' in printf not quoted */
macro1("x") /* error: func"x" not a func name */;
Instead I use a workaround with two args
#define macro2(a,b) void func##a(){ printf(b); }
However, the usage is not convincing:
macro2(x,"x");
macro2(a_long_name,"a_long_name");
