Testing/Debugging Only. Retrieves a pointer to the error
message corresponding to a specified error number. Use this
function on error numbers returned by pclOpen, pclWrite, and

Many error messages are longer than 20 characters. An
application must format the message before displaying it to
avoid truncation. See “Display” in Chapter 2 for more
information.

Error numbers that this function can retrieve

must be positive. Zero indicates success,

and negative numbers are ROM-DOS errors.

Pointer to a null-
terminated message string

0
