LazyProc is with its Call function. Looking at the documentation for DllGetClassObjectthe signature is. This means you have to pass these three parameters to proc. Call as uintptr s Call expects all arguments to be uintptr s. The ppv will in this case be a pointer to the COM object that you created. It uses go-ole and comutil library. This could be good starting point for other COM object use cases. How are we doing? Please help us improve Stack Overflow. Take our short survey. Learn more. Asked 3 years, 10 months ago.

The details vary depending on the underlying system, and by default, godoc will display the syscall documentation for the current system. The primary use of syscall is inside other packages that provide a more portable interface to the system, such as "os", "time" and "net". Use those packages rather than this one if you can. For details of the functions and data types in this package consult the manuals for the appropriate operating system. On most systems, that error has type syscall. Deprecated: this package is locked down. Callers should use the corresponding package in the golang. That is also where updates required by new systems or versions should be applied. CmsgLen returns the value to store in the Len field of the Cmsghdr structure, taking into account any necessary alignment. CmsgSpace returns the number of bytes an ancillary element with payload of the passed data length occupies. NetlinkRIB returns routing information base, as known as RIB, which consists of network facility information, states and parameters. ParseDirent parses up to max directory entries in buf, appending the names to names. It returns the number of bytes consumed from buf, the number of entries added to names, and the new names slice. ParseUnixRights decodes a socket control message that contains an integer array of open file descriptors from another process. If s contains a NUL byte this function panics instead of returning an error. If any string contains a NUL byte this function panics instead of returning an error. UnixCredentials encodes credentials into a socket control message for sending to another process. This can be used for authentication. UnixRights encodes a set of open file descriptors into a socket control message for sending to another process. Conn is implemented by some types in the net and os packages to provide access to the underlying file descriptor or handle. Credential holds user and group identities to be assumed by a child process started by StartProcess. An Errno is an unsigned number describing an error condition. It implements the error interface. The zero Errno is by convention a non-error, so code to convert from Errno to error should use:. Errno values can be tested against error values from the os package using errors. For example:. ParseNetlinkMessage parses b as an array of netlink messages and returns the slice containing the NetlinkMessage structures. ParseNetlinkRouteAttr parses m's payload as an array of netlink route attributes and returns the slice containing the NetlinkRouteAttr structures.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I'm trying to understand some of the low-level details of Golangs syscall package. In particular, I'm interested in Windows-specific system calls see the example below. Syscallsyscall. For instance, starting at line currently :. The go:linkname is the magic that makes this function be named syscall. Syscalleven though it's named runtime. These use DLLs loaded earlier to figure out how to really make the system calls. This is what c. Furthermore, special trickery is required to pass the parameters using the structure obtained by getc. How are we doing? Please help us improve Stack Overflow. Take our short survey.

Because Windows renumbers the system calls every hour or so ok, maybe every month or sonobody in his right mind actually uses them directly. The invocations always go through some DLL that uses unpublished Microsoft secrets to map from names to system-call numbers. Go appears to do the same thing, and further, generates code at build-time to make the calls to the DLLs, using github.

I'm trying to enumerate over a list of values in the Windows registry using Go, but I'm running into some trouble. In both cases, I'm having the same issue. This is the code I'm using which is currently using the win library from lxn :. A member of the Golang sub-reddit pointed out that I was not actually allocating any memory to the buffers passed in to RegEnumValue. As such, I've corrected the above example to the following:. Obviously, the "magic number" of 72 should probably be replaced with something else. There is another method called RegQueryInfoKey that can retrieve information about the registry key to allocate the correct number of bytes for the largest name and value in the key.
