Question

I need to pass a string literal to a function

myfunction("arg1" DEF_CHAR "arg1");

now part of that constructed string literal needs to be a function return

stmp = createString();
myfunction("arg1" stmp "arg2"); //oh that doesn't work either

is there any way to do this in one line?

myfunction("arg1" createString() "arg2"); //what instead?

NOTE: C only please.

My goal is to avoid initializing a new char array for this =/

You cannot build string literal at runtime, but you can create the string, like this:

char param[BIG_ENOUGH];

strcpy(param, "arg1");
strcat(param, createString());
strcat(param, "arg2");
myfunction(param);
