# $EPIC: write,v 1.3 2001/11/26 09:49:17 dinodrac Exp $
Synopsis:
   $write(<fd> <text>)
   $writeb(<fd> <text>)

Technical:
   This function writes the given text to the given file descriptor.  A
   newline is automatically appended to the text.  The $writeb() variant
   does the same thing, except the newline is not automatically appended.

   As a special case, a window refnum can be given as the file descriptor
   by prefixing the refnum with a w. This provides access to the logfile
   for that window. The reserved window refnum 0 can be used to address
   the current window's logfile, and the reserved window refnum -1 actually
   addresses the global logfile.

Practical:
   This function is useful for saving information to an external file.  It
   is most often used in scripts for saving configuration settings and the
   like.  The $writeb() function is useful for writing to binary files, or
   for writing lines to a file incrementally.

Returns:
     -1   if file descriptor does not exist
   > -1   number of bytes written (text length plus newline, if applicable)

Examples:
   $write(7 blah blah)                 writes "blah blah" plus NL to fd "7"
   $write(foo bar)                     "foo" not an fd, writes nothing
   $writeb(7 blah blah)                writes "blah blah" to fd "7"
   $writeb(foo bar)                    "foo" not an fd, writes nothing
   $write(w1 this is a test)       write to window refnum 1's logfile
   $write(w0 this is a test)       write to the current window's logfile
   $write(w-1 this is a test)      write to the global logfile
