To find the source code of API functions, follow these steps:
-
Understand the API: Identify the specific API function you need to locate. APIs can be part of a standard library (e.g., libc for C) or third-party libraries.
-
Check Documentation: Review the official documentation of the API. Many APIs provide links to their source code repositories or examples that reference the implementation.
-
Search Online: Use search engines with keywords like “API function name source code” or “library name source code.”
-
Explore Open-Source Projects: Visit platforms like GitHub, GitLab, or Bitbucket where developers often share libraries and frameworks. Look for repositories related to your API.
-
Use Reverse Engineering Tools: If the API is part of a binary library without public source code, use tools like Ghidra orIDA Pro to disassemble the binary and analyze the function calls.
By following these steps, you can effectively locate and study the source code of API functions.
