basic_ofstream: an output stream that wraps a file stream buffer. Provides functions to open or close a file in addition to those of generic output stream ofstream – operates on characters of type char; wofstream – operates on characters of type wchar_t; basic_ostringstream: an output stream that wraps a string stream buffer.
In the C++ programming language, seekg is a function in the fstream library (part of the standard library) that allows you to seek to an arbitrary position in a file. This function is defined for ifstream class - for ofstream class there's a similar function seekp (this is to avoid conflicts in case of classes that derive both istream and ostream, such as iostream).
The C programming language provides many standard library functions for file input and output.These functions make up the bulk of the C standard library header <stdio.h>. [1] The functionality descends from a "portable I/O package" written by Mike Lesk at Bell Labs in the early 1970s, [2] and officially became part of the Unix operating system in Version 7.
On Microsoft Windows, the core system dynamic libraries provide an implementation of the C standard library for the Microsoft Visual C++ compiler v6.0; the C standard library for newer versions of the Microsoft Visual C++ compiler is provided by each compiler individually, as well as redistributable packages. Compiled applications written in C ...
Shared-disk file systems (also called shared-storage file systems, SAN file system, Clustered file system or even cluster file systems) are primarily used in a storage area network where all nodes directly access the block storage where the file system is located. This makes it possible for nodes to fail without affecting access to the file ...
When a program creates a file, the file permissions are restricted by the mask. If the mask has a bit set to "1", then the corresponding initial file permission will be disabled. A bit set to "0" in the mask means that the corresponding permission will be determined by the program and the file system. In other words, the mask acts as a last ...
The CP/M file system (and also the original 8-bit FAT implemented in Microsoft BASIC) only recorded the lengths of files in multiples of 128-byte "records", so, by convention, a Control-Z character was used to mark the end of meaningful data if it ended in the middle of a record.
The program is also used to mount the new file system. At the time the file system is mounted, the handler is registered with the kernel. If a user now issues read/write/stat requests for this newly mounted file system, the kernel forwards these IO-requests to the handler and then sends the handler's response back to the user. Unmounting a FUSE ...
