- Works on python 2.7+ and python 3.2+ and pypy
- Currently exposes 23 low-level glibc functions (see below), 10 data types and 118 constants. All useful glibc features are in scope (patches welcome!)
from glibc import ...-- direct access to glibc constants, functions and types via lazy imports, fast startup, low memory overhead, efficient calls to glibc- Translates error codes according to documentation (manual pages) of each supported function. Raises OSError with appropriate values and a customized, easy-to-understand error message.
- Uses declarative "bindings", easy to verify for correctness, easy to add more types, functions and constants. Built-in tests verify the value of each constant, size and offset of each structure / union field and the size of the whole structure / union.
- Adds high-level abstractions on top of raw functions (pyglibc.select, pyglibc.signalfd, pyglibc.selectors, pyglibc.pthread_sigmask, pyglibc.pipe, pyglibc.subreaper) so that using them is easier and more pythonic.
- This code is entirely optional and users can still call the low-level C-equivalents directly.
- Where possible, existing Python APIs are followed so that glibc_select and glibc_selectors are drop-in replacements for the select and selectors modules from Python's standard library.
