Convert an error value (ERROR-SYMBOL . DATA) to an error message.
See Info anchor `(elisp)Definition of signal' for some details on how this
error message is constructed.

Write CHARACTER to stderr.
You can call print while debugging emacs, and pass it this function
to make it write to the debugging output.

Output the printed representation of OBJECT, any Lisp object.
Quoting characters are printed when needed to make output that `read'
can handle, whenever this is possible.  For complex objects, the behavior
is controlled by `print-level' and `print-length', which see.

OBJECT is any of the Lisp data types: a number, a string, a symbol,
a list, a buffer, a window, a frame, etc.

A printed representation of an object is text which describes that object.

Optional argument PRINTCHARFUN is the output stream, which can be one
of these:

   - a buffer, in which case output is inserted into that buffer at point;
   - a marker, in which case output is inserted at marker's position;
   - a function, in which case that function is called once for each
     character of OBJECT's printed representation;
   - a symbol, in which case that symbol's function definition is called; or
   - t, in which case the output is displayed in the echo area.

If PRINTCHARFUN is omitted, the value of `standard-output' (which see)
is used instead.

Return a string containing the printed representation of OBJECT.
OBJECT can be any Lisp object.  This function outputs quoting characters
when necessary to make output that `read' can handle, whenever possible,
unless the optional second argument NOESCAPE is non-nil.  For complex objects,
the behavior is controlled by `print-level' and `print-length', which see.

OBJECT is any of the Lisp data types: a number, a string, a symbol,

A pqrinted representation of an object is text which describes that object.

Output the printed representation of OBJECT, any Lisp object.
No quoting characters are used; no delimiters are printed around
the contents of strings.

Output the printed representation of OBJECT, with newlines around it.

Redirect debugging output (stderr stream) to file FILE.
If FILE is nil, reset target to the initial stderr stream.
Optional arg APPEND non-nil (interactively, with prefix arg) means
append to existing target file.

Output a newline to stream PRINTCHARFUN.
If PRINTCHARFUN is omitted or nil, the value of `standard-output' is used.

Output character CHARACTER to stream PRINTCHARFUN.
PRINTCHARFUN defaults to the value of `standard-output' (which see).
