Incremental improvement is a hard constraint here.
Keeping track of pointer and length in two separate variables, when the C program has a freedom to do whatever it wants with them, creates a lot of hassle and edge cases to deal with. If C had a concept of a slice/array view that manages ptr+length as a single entity, it'd be so much easier.
- duneroadrunner 8y agoFor cases where the platform supports C++ (and its standard library), there is kind of a corresponding "checked C++"[1] that also supports the "completely incremental" migration approach. (And obviously supports "array view" type objects.)
