# hx\_DelVarArg
## Description
Remove an argument of a variadic call. It is impossible to detect the correct number of variadic arguments in all cases, so the decompiler may detect too many arguments. This command allows you to correct such cases by decreasing the number of 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.
**Hotkeys**:
* Numpad- Delete variadic argument
If too many arguments are added to a variadic call, decompilation may [fail](/core/decompiler/failures.md). 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 **Edit → Other → Reset decompiler** information to reset the forced variadic argument counts.
