The origin must be one of the following constants that are defined in <stdio.h>: Origin Definition SEEK_SET Beginning of file SEEK_CUR Current position of file pointer SEEK_END End of fileFor a binary stream, you can also change the position beyond the end of the file. An attempt to...

This flag also causes the I/O system to maintain the file-position pointer. If this flag is set, the SYNCHRONIZE flag must be set in the DesiredAccess parameter. FILE_SYNCHRONOUS_IO_NONALERT (0x00000020) All operations on the file are performed synchronously. Waits in the system that ...
That name should not be used in new code. */ struct _IO_FILE { int _flags; /* High-order word is _IO_MAGIC; rest is flags. */ /* The following pointers correspond to the C++ streambuf protocol. */ char *_IO_read_ptr; /* Current read pointer */...
Each read or write operation moves position in file forwards to the end of read/written data (there is an underlying file position's indicator).Remark: Due to multibyte UTF-8 encoding, if current file's pointer does not point to beginning of multibyte sequence (see: UTF-16, emoji), ...
In a WDM device stack, only the functional device object (FDO) can use the two context pointers. File system drivers share this member across multiple opens to the same data stream. FsContext2 A pointer to whatever additional state a driver maintains about the file object; otherwise, NULL. ...
