During the +* development of the HTTP/FTP/SMTP support, it became aparent that +* error checking was taking a substantial amount of the coding. These +* function greatly simplify the task of checking errors. +* +* The main idea is that functions should return nil as its first return +* value when it finds an error, and return an error message (or value) +* following nil. In case of success, as long as the first value is not nil, +* the other values don't matter. +* +* The idea is to nest function calls with the "try" function.

Otherwise, it returns all values it received. +* +* The protect function returns a new function that behaves exactly like the +* function it receives, but the new function doesn't throw exceptions: it +* returns nil followed by the error message instead. +* +* With these two function, it's easy to write functions that throw +* exceptions on error, but that don't interrupt the user script. +* +* RCS ID: $Id: except.h,v 1.2 2005/09/29 06:11:41 diego Exp $ +\*=========================================================================*/ + +#include "lua.h" + +int except_open(lua_State *L); + +#endif |
