75 * This function converts an error code to an error message that is
76 * stored in the buffer starting at the location pointed to by
77 * message. The size of this buffer is specified by the size
78 * argument. If the error message is longer than size-1, it is
79 * truncated to that length. Regardless of whether the message is
80 * truncated or not, a final zero character that marks the end of the
81 * string is stored in the buffer. The function fails if the error
82 * code passed does not correspond to any of the fres error codes.
