Module: sys.platform.libc

Source: ./sys/platform/libc.reef

Overview

sys/platform/libc - Consolidated C Library FFI Declarations

This module provides a single source of truth for all libc FFI declarations used by the Reef standard library. Instead of each module declaring its own extern "C" functions, they import from here.

Categories:

• Memory: calloc, malloc, free, memcpy, memset, memmove
• String: strcpy, strcat, strlen
• Math: sin, cos, sqrt, pow, etc. (libm)
• I/O: Basic file operations (when not using reef_* wrappers)

Note: The libc/ module in stdlib is a separate, intentional wrapper for programs that want direct libc access. This module is for internal stdlib use.

For Reef runtime functions (reef_*), see sys/platform/runtime.reef
