/*
mksyscall_windows generates windows system call bodies
It parses all files specified on command line containing function
prototypes (like syscall_windows.go) and prints system call bodies
to standard output.
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 from it's winapi dll name,
the winapi name could be specified at the end, after "=" sign, like
//sys LoadLibrary(libname string) (handle uint32, err error) = LoadLibraryA
* Each function that returns err needs to supply a condition, that
return value of winapi will be tested against to detect failure.
This would set err to windows "last-error", otherwise it will be nil.
The value can be provided at end of //sys declaration, like
//sys LoadLibrary(libname string) (handle uint32, err error) [failretval==-1] = LoadLibraryA
and is [failretval==0] by default.
Usage:
mksyscall_windows [flags] [path ...]
The flags are:
-output
Specify output file name (outputs to console if blank).
-trace
Generate print statement after every syscall.

This program reads a file containing function prototypes
(like syscall_darwin.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 errno.
A line beginning with //sysnb is like //sys, except that the
goroutine will not be suspended during the execution of the system
call. This must only be used for system calls which can never
block, as otherwise the system call could cause all goroutines to
hang.

This program will generate three files and handle both gc and gccgo implementation:
- zsyscall_aix_ppc64.go: the common part of each implementation (error handler, pointer creation)
- zsyscall_aix_ppc64_gc.go: gc part with //go_cgo_import_dynamic and a call to syscall6
- zsyscall_aix_ppc64_gccgo.go: gccgo part with C function and conversion to C type.
The generated code looks like this
zsyscall_aix_ppc64.go
func asyscall(...) (n int, err error) {
// Pointer Creation
r1, e1 := callasyscall(...)
// Type Conversion
// Error Handler
return
}
zsyscall_aix_ppc64_gc.go

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
