/*
Most recent update:
5A(084), 16 Aug 94, fdc.
1. Fixed zoutdump() to work on Mac System 7.1 by removing
"flush_file_in_background()" call == PBFlushFile().
2. Fixed zopeni() to account for ZRFILE and to return an error if it is
called with an unknown file number, rather than pretending it succeeded.

Functions (n is one of the predefined file numbers from ckermi.h):
zopeni(n,name) -- Opens an existing file for input.
zopeno(n,name) -- Opens a new file for output.
zclose(n) -- Closes a file.
zchin(n) -- Gets the next character from an input file.
zinfill() -- (re) fill file input buffer, return the first character
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.
znewn(name,s) -- Make a new unique file name based on the given name.
zdelet(name) -- Delete the named file.
zxpand(string) -- Expands the given wildcard string into a list of files.
znext(string) -- Returns the next file from the list in "string".
zxcmd(cmd) -- Execute the command in a lower fork.
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.
