Subject: [Cocci] Searching for functions with negative return values as error indication
Date: Fri, 10 Apr 2020 17:07:36 +0200	[thread overview]
Message-ID: <146360ce-9cfb-e6f5-1601-fa95460c2cd5@web.de> (raw)

Hello,

Several functions for a programming language like C are designed in the way
that values are returned by an integral data type.
Specific value ranges can indicate then a failed function call.
A well-known variant of this design pattern is that negative return values
represent failures (while the other values can be used for succesful data processing.
Can the semantic patch language help any more to determine the list of
functions which use this style of error reporting in a selected code base?

Regards,
Markus
