The man page says they aren't suitable for sharing, so I wouldn't want to rely on them. –Kieran Tully Nov 7 '08 at 16:33 add a comment| up vote 0 down These do work even where shared POSIX semaphores don't (at least on the systems described above.). Looks like Windows doesn't support the SIGHUP signal. They are not yet documented. http://dssoundware.com/error-codes/enosys-error-number.php
Macro: int ESOCKTNOSUPPORT The socket type is not supported. Visualize sorting Is the NHS wrong about passwords? For example, attempting to remove a directory while another application is reading it. You get this error when you try to transmit data over a socket, without first specifying a destination for the data. http://www.gnu.org/s/libc/manual/html_node/Error-Codes.html
Note that you may need to actually try to USE the sema4 to see whether it works between processes. In cases like this, it's important to check your input data for sanity, or check errno after every call.EROFS -- You attempted to modify a file or directory stored on a Macro: int ENOTEMPTY Directory not empty, where an empty directory was expected. I think you may just need to upgrade your kernel or maybe even librt.
I think /dev/shm is necessary too but sem_open() is failing before that, and strace supports this. # /* Quick'n'dirty test program to illustrate sem_open failure #Run this file to auto-build test Macro: int ERESTART Macro: int ECHRNG Macro: int EL2NSYNC Macro: int EL3HLT Macro: int EL3RST Macro: int ELNRNG Macro: int EUNATCH Macro: int ENOCSI Macro: int EL2HLT Macro: int EBADE Macro: This article familiarizes you with UNIX error reporting in the standard C library and (hopefully) encourages you to report and handle errors in a user-friendly way.Let's dig in!Back to topBefore you Linux Errno Example Macro: int ENETDOWN A socket operation failed because the network was down.

I'm going to be working in Eclipse using the C/C++ Development Tooling (CDT).
The system does not guarantee that it will notice all such situations. C Programming Error Codes Before I wrote my "answer" I verified that sem_init(pshared=0) can create unshared semaphores on the affected systems. Macro: int EINPROGRESS An operation that cannot complete immediately was initiated on an object that has non-blocking mode selected. See Connecting.

Vadorequest commented Sep 22, 2013 I mean that there is no error when I *sails lift* the github project, even if the error appears when I *sails lift* my own project. Error Eintr This is used to indicate various kinds of problems with passing the wrong argument to a library function. Linux Kernel Error Codes You can use the select function to find out when the pending operation has completed; see Waiting for I/O.
The errno variable may be implemented as a macro, but you can always examine or set it as if it were a simple integer variable. You can simulate this yourself by using a printf() call and the strerror() function, which returns a pointer to the textual representation of the current errno value.One detail you can't see Macro: int ENETRESET A network connection was reset because the remote host crashed.

Let's take a look at some additional error-related global variables and the standard defined by POSIX-1003.1 errno values.Back to topError global variables and standard valuesSo, the global errno variable is set Eintr Errno Learn more. For more information, see "Local storage for private data" in the documentation for ThreadCreate().
Macro: int ENOPROTOOPT You specified a socket option that doesn’t make sense for the particular protocol being used by the socket. [email protected] [email protected] Windows 7 32-bit drosen0 referenced this issue Sep 26, 2013 Closed Change SIGHUP to SIGINT to support Windows #925 sgress454 closed this Dec 16, 2013 ZeeshanVbase commented Sep 28, It is probably a good idea to delay for a few seconds before trying it again, to allow time for other processes to release scarce resources. Eintr Signal If you're lucky, the function's man page lists all of its possible return values and what they mean in the context of this particular function.
Macro: int ESHUTDOWN The socket has already been shut down. The runtime library never resets errno to 0. A temporary resource shortage made an operation impossible. joey-qc commented Sep 21, 2013 Same experience, same error.
See Job Control, for information on process groups and these signals. Reload to refresh your session. You signed in with another tab or window. The first is the number of standard error messages stored in sys_errlist.
It will not work with modern versions of the C library. Do you get the same error with "SIGINT"? Do you get the same error with "SIGINT"? To translate a numeric error code to an error message, use os.strerror().

Macro: int EOPNOTSUPP The operation you requested is not supported. Macro: int EADDRNOTAVAIL The requested socket address is not available; for example, you tried to give a socket a name that doesn’t match the local host name.
You signed out in another tab or window. Macro: int ECONNREFUSED A remote host refused to allow the network connection (typically because it is not running the requested service). Some socket functions don’t make sense for all types of sockets, and others may not be implemented for all communications protocols. share|improve this answer answered Nov 7 '08 at 16:15 community wiki bog Thanks.
Note that an empty directory still contains the .
