Summary: process::io::write takes parameter as void* which could be const Key: MESOS-3795 URL: https://issues.apache.org/jira/browse/MESOS-3795 Project: Mesos Issue Type: Improvement Components: libprocess Reporter: Benjamin Bannier In libprocess we have {code} Future<size_t> write(int fd, void* data, size_t size); {code} which expects a non-{{const}} {{void*}} for its {{data}} parameter. Under the covers {{data}} appears to be handled as a {{const}} (like one would expect from the signature its inspiration {{::write}}). This function is not used too often, but since it expects a non-{{const}} value for {{data}} automatic conversions to {{void*}} from other pointer types are disabled; instead callers seem cast manually to {{void*}} -- often with C-style casts. We should sync this method's signature with that of {{::write}}. In addition to following the expected semantics of {{::write}}, having this work without casts with any pointer value {{data}} would make it easier to interface this with character literals, or raw data ptrs from STL containers (e.g. {{Container::data}}). It would probably also indirectly eliminate temptation to use C-casts. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
