"WASI Libc is a libc for WebAssembly programs built on top of WASI
|
|
system calls. It provides a wide array of POSIX-compatible C APIs, including
|
|
support for standard I/O, file I/O, filesystem manipulation, memory
|
|
management, time, string, environment variables, program startup, and many
|
|
other APIs.")
