Install: brew install cproto

About:
cproto scans C, C++, and Lex/Yacc source files to automatically generate function prototypes. It analyzes function definitions and declarations to produce ANSI C or traditional K&R style prototypes. This tool is invaluable for maintaining header files and modernizing legacy codebases.

Key Features:

Supports C, C++, Lex, and Yacc source files
Generates ANSI C or K&R style prototypes
Handles function declarations across multiple files
Outputs to stdout for easy redirection to header files

Use Cases:

Generating header files from existing C source code
Modernizing legacy K&R C code to ANSI C standards
Verifying function signatures across a large codebase

Alternatives:

cscope – cscope is for code navigation, while cproto specifically generates prototypes
Doxygen – Doxygen generates full documentation, cproto focuses on raw prototypes
