- * The parameter lists must give a type for each argument:

- This program reads a file containing function prototypes
- (like syscall_solaris.go) and generates system call bodies.
- The prototypes are marked by lines beginning with "//sys"
- and read like func declarations if //sys is replaced by func, but:
- * The parameter lists must give a name for each argument.
- This includes return parameters.
- * The parameter lists must give a type for each argument:
- the (x, y, z int) shorthand is not allowed.
- * If the return parameter is an error number, it must be named err.
- * If go func name needs to be different than its libc name,
- * or the function is not in libc, name could be specified
- * at the end, after "=" sign, like
- //sys getsockopt(s int, level int, name int, val uintptr, vallen *_Socklen) (err error) = libsocket.getsockopt
