Supported C-Language Features

This section provides a summary of supported C language features pymwp can analyze. It also lists language features that are in the process of being implemented and for which implementation is planned.

Note on C file parsing

pymwp uses pycparser to process the C input file. Any limitation of pycparser is also a limitation in pymwp. From pycparser website: "pycparser aims to support the full C99 language (according to the standard ISO/IEC 9899). Some features from C11 are also supported."

Analysis will bypass any unsupported statement and raises a warning.
