Coding guidelines:
|
|
|
|
|
|
|
|
|
|
* Use enum for constants where appropriate
|
|
|
|
|
* Use const as much as possible (where appropriate)
|
|
|
|
|
* Use C99 data types (intN_t, uintN_t, bool)
|
|
|
|
|
* Hide data-types in .c files where possible (use struct foo)
|
|
|
|
|
* Avoid malloc/free, use mem_alloc/mem_deref instead
|
|
|
|
|
* CVS/svn/git tags are NOT allowed in the code!
|
|
|
|
|
* Avoid bit-fields in structs which are not portable
|
|
|
|
|
* Use dummy handlers for timing-critical callbacks
|
|
|
|
|
* return err, return alloced objects as pointer-pointers
|
|
|
|
|
* in allocating functions, first arg is always double pointer
|
|
|
|
|
* Use POSIX error-codes; EINVAL for invalid args, EBADMSG for
|
|
|
|
|
parse errors and EPROTO for protocol errors
