Overload A Function For A Virtual Table

+
+
+int sqlite3_overload_function(sqlite3*, const char *zFuncName, int nArg);
+
+

+Virtual tables can provide alternative implementations of functions +using the xFindFunction method of the virtual table module. +But global versions of those functions +must exist in order to be overloaded.

+ +

This API makes sure a global version of a function with a particular +name and number of parameters exists. If no such function exists +before this API is called, a new function is created. The implementation +of the new function always causes an exception to be thrown. So +the new function is not good for anything by itself. Its only +purpose is to be a placeholder function that can be overloaded +by a virtual table. +

See also lists of + Objects, + Constants, and + Functions.
