I think BSDi has been fixing this, at least for use with their login
classes. passwd(5) login classes are used as an index into a termcap-
style database, but they've definitely cleaned up the code and allow
for long capability names.
I don't know whether they've done it as a `generic' XXXcap library, or
only for the login classes.
Our current way of doing things is a crock. Consider
/usr/src/usr.sbin/lpr/common_source/printcap.c:
...
/*
* termcap - routines for dealing with the terminal capability data base
^^^^^^^ ^^^^^^^^^^^^^^^^^^^
*
...
#define PRINTCAP
...
if (bp >= tbuf+BUFSIZ) {
write(2, "Termcap entry too long\n", 23);
*bp = '\0';
...
cp = getenv("TERMCAP");
/*
* TERMCAP can have one of two things in it. It can be the
...
if (cp && *cp) {
if (*cp!='/') {
cp2 = getenv("TERM");
if (cp2==(char *) 0 || strcmp(name,cp2)==0) {
strcpy(bp,cp);
return(tnchktc());
} else {
tf = open(_PATH_PRINTCAP, 0);
}
} else
tf = open(cp, 0);
}
if (tf==0)
tf = open(_PATH_PRINTCAP, 0);
#else
tf = open(_PATH_PRINTCAP, 0);
#endif
...or /usr/src/usr.bin/vgrind/vgrindefs.c:
/*
* Get an entry for terminal name in buffer bp,
* from the termcap file. Parse is very rudimentary;
* we just notice escaped newlines.
*/
tgetent(bp, name, file)
char *bp, *name, *file;
{
...
Just to name two of them. (In addition, the code there is a clear
candidate for the IOCCC. I wonder whether Bill Joy did ever
participate in it...)

Never trust an operating system you don't have sources for. ;-)
