libc: Implement wrappers for sys_{open,read,write} read() and close() are in unistd.h, but open() in fnctl.h. I thought only the definitions for O_SOMETHING were in fnctl.h, but it is as it is. Don't know why, but let's not anger the Unix gods. The FILE* C API is pending as well. 2022-10-10 18:45:26 +00:00			`#ifndef _FCNTL_H`
