Add/del variadic arguments

Hotkeys

Numpad+

Add variadic argument

Numpad-

Delete variadic argument

This command adds or removes an argument of a variadic call. It is impossible to detect the correct number of variadic arguments in all cases, and this command can be used to fix wrongly detected arguments. It is available only when the cursor is located on a call to a variadic function (like printf). The decompiler automatically detects the argument locations, the user can only increase or decrease their number.

This command is useful if the decompiler determines the number of arguments incorrectly. For example:

        printf("This is a test call: %d\n");

apparently lacks an argument. Pressing Numpad+ modifies it:

        printf("This is a test call: %d\n", v1);

If too many arguments are added to a variadic call, decompilation may . Three methods to correct this situation exist:

undo the last action (hotkey Ctrl-Z)
position the cursor on the wrongly modified call and press Numpad-
or use to reset the forced varidic argument counts.
