/*
mkwinsyscall 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 its 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.
- If the function name ends in a "?", then the function not existing is non-
fatal, and an error will be returned instead of panicking.
Usage:
mkwinsyscall [flags] [path ...]
Flags
-output string
Output file name (standard output if omitted).
-sort
Sort DLL and function declarations (default true).
Intended to help transition from older versions of mkwinsyscall by making diffs
easier to read and understand.
-systemdll
Whether all DLLs should be loaded from the Windows system directory (default true).
-trace
Generate print statement after every syscall.
-utf16
Encode string arguments as UTF-16 for syscalls not ending in 'A' or 'W' (default true).
-winio
Import this package ("github.com/Microsoft/go-winio").
