An error occurred while writing the module.

An error occurred while writing the module-general Linux technology-Linux programming and kernel information. The following is a detailed description. It is a simple module, but an error occurs. It uses a red hat 9. The code is
Define MODULE
# Include

Int init_module (void) {printk ("<1> hello world \ n"); return 0 ;}
Void cleanup_module (void) {printk ("<2> goodbye world \ n "):}

Error message:
Hello. c: 1: parse error before "MODULE"
In file include from hello. c: 2:
/Usr/include/linux/module. h: 26: syntax error before "struct"

Hope you can solve it. I just learned it.
