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 ...

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), ...
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 */...
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. ...
File access mode flag "b" can optionally be specified to open a file in binary mode. This flag has effect only on Windows systems. On the append file access modes, data is written to the end of the file regardless of the current position of the file position indicator. ...
CInternetFile::Seek Repositions the pointer in an open file. CInternetFile::SetReadBufferSize Sets the size of the buffer where data will be read. CInternetFile::SetWriteBufferSize Sets the size of the buffer where data will be written. CInternetFile::Write Writes the number of specified...
