How to find all C functions starting with a prefix in a library
To find all C functions starting with a specific prefix in a library, you can use different approaches depending on your development environment and tools. Here are a few common methods:
Using nm (Unix-like systems):
On Unix-like systems (e.g., Linux, macOS), you can use thenm
command-line tool to list symbols from object files or libraries. You can filter the output to find functions starting with a specific prefix. Here's an example:perlnm -g <library_file> | grep "^<prefix>"
Replace
<library_file>
with the path to your library file and<prefix>
with the desired prefix for the functions. This command will list all symbols in the library and filter out the functions starting with the specified prefix.Using objdump (GNU binutils):
Theobjdump
tool from the GNU binutils package provides a similar functionality tonm
. You can use the-t
option to display the symbol table and filter the output withgrep
or other command-line tools. Here's an example:perlobjdump -t <library_file> | grep "^<prefix>"
Replace
<library_file>
with the path to your library file and<prefix>
with the desired prefix for the functions.Using Visual Studio (Windows):
If you are using Visual Studio on Windows, you can use the "Dumpbin" utility, which is part of the Visual Studio toolset. Open the Developer Command Prompt for Visual Studio and run the following command:mathematicadumpbin /SYMBOLS <library_file> | findstr /R /C:"^<prefix>"
Replace
<library_file>
with the path to your library file and<prefix>
with the desired prefix for the functions. This command will list the symbols in the library and filter out the functions starting with the specified prefix.Using IDE or editor plugins:
Some IDEs and code editors have plugins or extensions that provide symbol search functionality. These plugins can help you search for functions starting with a specific prefix within a library. Examples include the "ctags" plugin for Vim or Emacs and various symbol search plugins for IDEs like Visual Studio Code, Eclipse, or JetBrains IDEs.
These methods should help you find C functions starting with a specific prefix in a library. Choose the method that suits your development environment and tools.
