go.sys/windows: use $GOROOT/src/pkg/syscall/mksyscall_windows.go to generate syscalls
Also zsyscall_windows_386.go and zsyscall_windows_amd64.go have same contents, so merge them into single file. LGTM=r R=r CC=golang-codereviews https://golang.org/cl/124430043

# The windows package provides access to the raw system call

# a new architecture/operating system combination requires

# some manual effort, though there are tools that automate
|

# much of the process. The auto-generated files have names
|

# beginning with z.
|

# This script runs or (given -n) prints suggested commands to generate z files

# * asm_${GOOS}_${GOARCH}.s
|
||||
#
|
||||
# This hand-written assembly file implements system call dispatch.
|
||||
# There are three entry points:
|
||||
#
|
||||
# func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
|
||||
# func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr);
|
||||
# func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
|
||||
#
|
||||
# The first and second are the standard ones; they differ only in
|
||||
# how many arguments can be passed to the kernel.
|
||||
# The third is for low-level use by the ForkExec wrapper;
|
||||
# unlike the first two, it does not call into the scheduler to
|
||||
# let it know that a system call is running.
|
||||
#
|
||||
# * syscall_${GOOS}.go
|
||||
#
|
||||
# This hand-written Go file implements system calls that need
|
||||
# special handling and lists "//sys" comments giving prototypes
|
||||
# for ones that can be auto-generated. Mksyscall reads those
|
||||
# comments to generate the stubs.
|
||||
#
|
||||
# * syscall_${GOOS}_${GOARCH}.go
|
||||
#
|
||||
# Same as syscall_${GOOS}.go except that it contains code specific
|
||||
# to ${GOOS} on one particular architecture.
|
||||
#
|
||||
# * types_${GOOS}.c
|
||||
#
|
||||
# This hand-written C file includes standard C headers and then
|
||||
# creates typedef or enum names beginning with a dollar sign
|
||||
# (use of $ in variable names is a gcc extension). The hardest
|
||||
# part about preparing this file is figuring out which headers to
|
||||
# include and which symbols need to be #defined to get the
|
||||
# actual data structures that pass through to the kernel system calls.
|
||||
# Some C libraries present alternate versions for binary compatibility
|
||||
# and translate them on the way in and out of system calls, but
|
||||
# there is almost always a #define that can get the real ones.
|
||||
# See types_darwin.c and types_linux.c for examples.
|
||||
#
|
||||
# * zerror_${GOOS}_${GOARCH}.go
|
||||
#
|
||||
# This machine-generated file defines the system's error numbers,
|
||||
# error strings, and signal numbers. The generator is "mkerrors.sh".
|
||||
# Usually no arguments are needed, but mkerrors.sh will pass its
|
||||
# arguments on to godefs.

/*
|
||||
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:
|
||||
-trace
|
||||
Generate print statement after every syscall.
