[PATCH v8 5/6] convert: move multiple file filter error handling to separate function

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Refactoring the filter error handling is useful for the subsequent patch
'convert: add "status=delayed" to filter process protocol'.

In addition, replace the parentheses around the empty "if" block with a
single semicolon to adhere to the Git style guide.
