CodeQL library for C/C++

Member predicate StrcatFunction::hasOnlySpecificWriteSideEffects

Holds if the function never writes to memory that remains allocated after the function returns. This memory could be from global variables, or from other memory that was reachable from a pointer that was passed into the function. Output side-effects, and writes to memory that cannot be visible to the caller (for example a buffer inside an I/O library) are not modeled here.
