/* chartostring.c: change a character (i.e., an integer) to a one-character string. Written in 1994 by Karl Berry.

And we need to keep it that way because that's how xord is initialized, etc. But sometimes we want one-character strings -- e.g., in tangle.ch and weave.ch. There's no real alternative to wasting the two bytes of memory (plus malloc overhead) here, but it doesn't matter. */ string chartostring (char ch) { string str = xmalloc (2); str[0] = ch; str[1] = 0; return str; }
