Cfile header file

Also, many standard library headers do not have. Don't put using statements in your header files! We include the header file so that the compiler pulls in the declaration. After the compiler finishes compiling each. Typically, header files have an include guard or a pragma once directive to ensure that they are not inserted multiple times into a single. Because a header file might potentially be included by multiple files, it cannot contain definitions that might produce multiple definitions of the same name.

The following are not allowed, or are considered very bad practice:. Use of the using directive will not necessarily cause an error, but can potentially cause a problem because it brings the namespace into scope in every. Restrict Go. NewServer Go. ExtTagParser Java.

The CFile class provides the Attribute enumeration type so file attributes can be specified symbolically:. Locking bytes in a file prevents access to those bytes by other processes. You can lock more than one region of a file, but no overlapping regions are allowed. When you unlock the region using the UnlockRange member function, the byte range must correspond exactly to the region that was previously locked.

The LockRange function doesn't merge adjacent regions. If two locked regions are adjacent, you must unlock each region separately. It contains CFile::hFileNull , an operating-system-independent empty file indicator, if the handle hasn't been assigned. Open is designed for use with the default CFile constructor. The path can be relative, absolute, or a network name UNC. It specifies the action to take when opening the file. You can combine options by using the bitwise-OR operator.

One access permission and one share option are required; the modeCreate and modeNoInherit modes are optional. See the CFile constructor for a list of mode options. Nonzero if the open was successful; otherwise 0. The pError parameter is meaningful only if 0 is returned. The two Open functions are "safe" methods for opening a file, where a failure is a normal, expected condition. Open can still initialize a CFileException object to describe the error, however.

If you pass a pointer to an existing CFileException , and Open encounters an error, the function fills it with information describing that error. Open doesn't throw an exception in either case. For text-mode files, carriage return-line feed pairs are counted as single characters. The number of bytes transferred to the buffer. For all CFile classes, the return value may be less than nCount if the end of file was reached.

The path can be relative or absolute, and can contain a network name. The Remove member function throws an exception if the connected file is open or if the file can't be removed. This function is equivalent to the DEL command. Positive values move the file pointer towards the end of the file; negative values move the file pointer towards the start of the file. The position of the file pointer if the method was successful; otherwise, the return value is undefined and a pointer to a CFileException exception is thrown.
