C-Kermit's OS/2 support originally by Chris Adie <C.Adie@uk.ac.edinburgh>
Edinburgh University Computing Service, Scotland, for C-Kermit 4F. Adapted
to C-Kermit 5A and integrated into the UNIX support module by Kai Uwe Rommel
<rommel@informatik.tu-muenchen.de>, Muenchen, Germany, December 1991.
And then split away from the Unix modules for C-Kermit 6.1 because the
amount of disparate code was just too great.

/*
Directory Separator macros, to allow this module to work with both UNIX and
OS/2: Because of ambiguity with the command line editor escape \ character,
the directory separator is currently left as / for OS/2 too, because the
OS/2 kernel also accepts / as directory separator. But this is subject to
change in future versions to conform to the normal OS/2 style.
Win32 also allows the Directory Separator to be / when it is used for
local disk operations. However, if a UNC is in use, then \ must be used.
So we have two choices, we can return UNC names with \ quoted which might
break if the command quoting is turned off, or we can performed the reverse
translation in all file i/o functions if the first two characters are "//"
indicating a UNC.

Functions (n is one of the predefined file numbers from ckcker.h):
zopeni(n,name) -- Opens an existing file for input.
zopeno(n,name,attr,fcb) -- Opens a new file for output.
zclose(n) -- Closes a file.
zchin(n,&c) -- Gets the next character from an input file.
zsinl(n,&s,x) -- Read a line from file n, max len x, into address s.
zsout(n,s) -- Write a null-terminated string to output file, buffered.
zsoutl(n,s) -- Like zsout, but appends a line terminator.
zsoutx(n,s,x) -- Write x characters to output file, unbuffered.
zchout(n,c) -- Add a character to an output file, unbuffered.
zchki(name) -- Check if named file exists and is readable, return size.
zchko(name) -- Check if named file can be created.
zchkspa(name,n) -- Check if n bytes available to create new file, name.
znewn(name,s) -- Make a new unique file name based on the given name.
zdelet(name) -- Delete the named file.
nzxpand(string,flags) -- Expands the given wildcard string into a list of files.
znext(string) -- Returns the next file from the list in "string".
zxcmd(n,cmd) -- Execute the command in a lower fork on file number n.
zclosf() -- Close input file associated with zxcmd()'s lower fork.
zrtol(n1,n2) -- Convert remote filename into local form.
zltor(n1,n2) -- Convert local filename into remote form.
zchdir(dirnam) -- Change working directory.
zhome() -- Return pointer to home directory name string.
zkself() -- Kill self, log out own job.
zsattr(struct zattr *) -- Return attributes for file which is being sent.
zstime(f, struct zattr *, x) - Set file creation date from attribute packet.
zrename(old, new) -- Rename a file.
zlink(source,destination) -- Link a file.
zcopy(source,destination) -- Copy a file.
zmkdir(path) -- Create the directory path if possible
zfnqfp(fname,len,fullpath) - Determine full path for file name.
