wiiulegacy/libutils repository overview

⁠libutils for WiiU homebrew.

This is a library for common functions.

⁠Features

• FS utility functions
• Wrapper for easy kernel read/write (KernelCopyData to copy data to any place)
• Multiple language support via gettext
• Common system functions (Exception handler, memory functions, Thread wrapper etc.)
• Built in function patcher engine
• String tools

(For some features the application need to be loaded from the homebrew_launcher to have kernel access)

⁠Logging usage

To able to use the logging, you need to compile the target application with follow C/C++ flag:

  -D__LOGGING__

Usage in the application:

log_init(); // Enables broadcast logging.
printf("Just prints this text\n");
DEBUG_FUNCTION_LINE("This prints my current function, file and line\n");

Read the logs via the udp_debug_reader⁠.

⁠Usage (TODO)

Link the application with

-lutils -ldynamiclibs

You also need to add the include path to your Makefile. Example:

export INCLUDE	:= [...]  -I$(PORTLIBS)/include/libutils

Check out the header for more information.

⁠Compiling

For compiling and using this lib, you need the dynamic_libs⁠ installed to your portlibs folder.

Install this static library into your portlibs folder via:

make && make install

⁠Dependencies

• Application needs to be loaded from the homebrew_launcher⁠
• dynamic_libs⁠ for access to the functions.
