Simplified version of LibC suitable for supporting WCPL code. Relies on WASI for system interface functionality, but can be used without it if none of the WASI-dependent functions are invoked by the program.
The library is represented as a collection of traditional header files and (for functionality that can't be implemented directly in the header file) object modules. Files and modules are coordinated by module name which serves as the base of the file names for header, object, and source files. For traditional header include names that have internal slashes, module names contain dots in place of slashes.
Please note that currently WCPL cannot link multiple modules with the
same module name, so please make sure that your source files do not
have names like stdio.c. This limitation may be lifted in the future.
