Aug 06, 2013 · ioctl() Errno Numbers. Hi there, I'm trying to run a testing program on a PPC platform running RHLE 8.0. The test program doesn't work propperly and complains with ioctl commands can return negative error codes as documented in errno(3); these get turned into errno values in user space. On success, the return code should be zero. It is also possible but not recommended to return a positive ‘long’ value. If the output buffer is not large enough for a socket handle (the cbOutBuffer is less than the size of a SOCKET) or the lpvOutBuffer parameter is a NULL pointer, SOCKET_ERROR is returned as the result of this IOCTL and WSAGetLastError returns WSAEFAULT. Macros and defines used in specifying an ioctl() request are located in the file . Return Value Usually, on success zero is returned. A few ioctl() requests use the return value as an output parameter and return a nonnegative value on success. On error, -1 is returned, and errno is set appropriately. Errors EBADF d is not a valid Feb 20, 2012 · I have a Kingston Data traveler 16GB pen drive, which worked fine for quite a while, my friend who borrowed the drive may have botched up on formatting it, as now the drive asks to be formatted for use but unable to do so. trying to format it via DOS gives an IOCTL error, and 3rd party software cannot seem to detect the drive to get viable solution. Neither can disk management (Windows 7), but IOCTL_DISK_GET_DRIVE_LAYOUT_EX IOCTL. 12/05/2018; 2 minutes to read; In this article. Retrieves extended information for each entry in the partition tables for a disk. To perform this operation, call the DeviceIoControl function with the following parameters. You must have read access to the drive in order to use this control code. In particular, many operating characteristics of character special files (e.g. terminals) may be controlled with ioctl() requests. The argument fildes must be an open file descriptor. An ioctl request has encoded in it whether the argument is an ``in'' parameter or ``out'' parameter, and the size of the argument argp in
