How do I concatenate const/literal strings in C?

Question

I\'m working in C, and I have to concatenate a few things.

Right now I have this:

message = strcat(\"TEXT \", var);

message2 = strcat(strcat(\"TEXT

Best way to do it without having a limited buffer size is by using asprintf()

char* concat(const char* str1, const char* str2)
{
    char* result;
    asprintf(&result, "%s%s", str1, str2);
    return result;
}
