codes can’t occur on GNU systems, but they can occur using the GNU C Library on other systems. Macro: int EPERM Operation not permitted; only the owner of the
Errno.h Windows
file (or other resource) or processes with special privileges can perform the operation.
Einval Errno
Macro: int ENOENT No such file or directory. This is a “file doesn’t exist” error for ordinary files that are ewouldblock referenced in contexts where they are expected to already exist. Macro: int ESRCH No process matches the specified process ID. Macro: int EINTR Interrupted function call; an asynchronous signal occurred and prevented completion http://www-numi.fnal.gov/offline_software/srt_public_context/WebDocs/Errors/unix_system_errors.html of the call. When this happens, you should try the call again. You can choose to have functions resume after a signal that is handled, rather than failing with EINTR; see Interrupted Primitives. Macro: int EIO Input/output error; usually used for physical read or write errors. Macro: int ENXIO No such device or address. The system tried to use the device represented by a file you http://www.gnu.org/s/libc/manual/html_node/Error-Codes.html specified, and it couldn’t find the device. This can mean that the device file was installed incorrectly, or that the physical device is missing or not correctly attached to the computer. Macro: int E2BIG Argument list too long; used when the arguments passed to a new program being executed with one of the exec functions (see Executing a File) occupy too much memory space. This condition never arises on GNU/Hurd systems. Macro: int ENOEXEC Invalid executable file format. This condition is detected by the exec functions; see Executing a File. Macro: int EBADF Bad file descriptor; for example, I/O on a descriptor that has been closed or reading from a descriptor open only for writing (or vice versa). Macro: int ECHILD There are no child processes. This error happens on operations that are supposed to manipulate child processes, when there aren’t any processes to manipulate. Macro: int EDEADLK Deadlock avoided; allocating a system resource would have resulted in a deadlock situation. The system does not guarantee that it will notice all such situations. This error means you got lucky and the system noticed; it might just hang. See File Locks, for an example. Macro: int

EFAULT error in accept socket call P: n/a Rookie Hi, I was writing a simple program using sockets. The program is supposed to be a TCP server that receives a string sent by the client. For this purpose I defined a char error codes array called readString which was initially defined as readString[6]. The program worked fine. I then increased the array size to readString[100] and the accept socket call started giving an error (errno=14;EFAULT). This gave me the impression that the clientAddr structure was causing this problem, so I declared it as a global variable(see linux kernel error below).Now the code works fine. Can someone tell me why I am getting this error? Your help would be greatly appreciated. Thanks. The following is a brief outline of the code: struct sockaddr_in clientAddr; //Declaring this here works when I increase readString from readString[6] to readString[100] int main() { char readString[100],*tempPtr; struct sockaddr_in serverAddr;//,clientAddr; /*Declaring clientAddr here does not work when I increase readString from readString[6] to readString[100]. It gives an EFAULT error for accept. This works fine for readString[6]*/ .. .. .. if((serverSockFd=socket(AF_INET,SOCK_STREAM,0))<0) .. .. .. if(bind(serverSockFd,(struct sockaddr*)&serverAddr, sizeof(serverAddr))<0) .. .. .. if(listen(serverSockFd,5)<0) .. .. .. if((clientSockFd=accept(serverSockFd,(struct sockaddr*)&clientAddr,&clientAddrSize))<0) .. .. .. } Here is the full text of the code, in case the above does not suffice: //struct sockaddr_in clientAddr; int main() { int serverSockFd,clientSockFd,noOfBytesReadTotal,noOfB ytesReadOneRead; char readString[100],*tempPtr; socklen_t clientAddrSize; struct sockaddr_in serverAddr; struct sockaddr_in clientAddr; strcpy(readString,"Hello World!"); printf("Before receiving from client readString = %s\n",readString); if((serverSockFd=socket(AF_INET,SOCK_STREAM,0))<0) { printf("Socket failed\n"); exit(1); } else
