char *dberror(void)
Return:
This function returns a pointer to a string containing the text of the
most recent DB library error message (or to a string containing the DB
library version number, if there have been no errors). Function
dberror is primarily intended for use in applications for which the
standard error output is unavailable or inadequate, such as in X Window
System applications. (Note that this function may be unnecessary for
MS-Windows applications, since the MS-Windows version of the DB library
generates a message box for error messages, unless dbquiet has
been used to silence them.) This function was first introduced in DB
library version 4.5. Versions earlier than 9.4 return an empty string
rather than the library version number if there have been no errors.
