I became interested in the use case to consider more type definitions
besides the ones which should usually be handled for Linux source files.

How do you think about to make this source code analysis parameter configurable?


>>> +{unsigned char, unsigned short int, unsigned int, unsigned long, unsigned long long, size_t, u8, u16, u32, u64} v;

How does the data type "size_t" fit into the suggested SmPL approach?

Would you like to reuse your approach for checking of more software eventually?

Markus
