For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This is done because using fseek and ftell to move within a file that ends with a CTRL+Z, may cause fseek to behave improperly near the end of the file. If you C use strerror(int errno) declared in string.h Code: #include ....

It is deleted when the last file pointer is closed.ccs=ENCODINGSpecify the coded character set to use (UTF-8, UTF-16LE, and UNICODE) for this file. a bullet shot into a suspended block Logical fallacy: X is bad, Y is worse, thus X is not bad Largest number of eɪ sounds in a word Why was the The primary use of the freopen() function is to change the file associated with a standard text stream (stderr, stdin, or stdout). e (since glibc 2.7) Open the file with the O_CLOEXEC flag.

After appending has occurred, the MS-DOS TYPE command only shows data up to the original EOF marker and not any data that's appended to the file. For example, on Solaris, you often end up with errno set to ENOTTY after a successful operation, because stdout is not connected to a terminal. If you do not specify the 'b' flag when working with binary files, you may experience strange problems with your data, including broken image files and strange problems with \r\n characters. cEnable the commit flag for the associated filename so that the contents of the file buffer are written directly to disk if either fflush or _flushall is called.nReset the commit flag

Output operations always write data at the end of the file, expanding it. Where's the test for NULL? –David Schwartz Apr 1 '13 at 22:35 1 take a look at strerror() which return a string that explains errno for you. –Zaffy Apr 1

Thanks. The file must exist. "w+"write/update: Create an empty file and open it for update (both for input and output). For example, your code should be: if ((dfile = fopen(debugText, "w")) == 0) ...then fopen() failed and errno is relevant... Dev centers Windows Office Visual Studio Microsoft Azure More...

In order to open a file as a binary file, a "b" character has to be included in the mode string. Inside a C program, when a function fails, you should handle the errors accordingly, or at least record the errors in a log file. Code: BOOL bReadFile( BYTE* p, INT32& nSize, CString strFilename) { CFile cfSessionFile; CFileException ex; if (cfSessionFile.Open( strFilename, CFile::modeRead, &ex)) { nSize = (INT32) cfSessionFile.GetLength(); if((p != NULL) && (nSize > 0)) Contact Us - Advertising Info - Rules - LQ Merchandise - Donations - Contributing Member - LQ Sitemap - Main Menu Linux Forum Android Forum Chrome OS Forum Search LQ

However, output shall not be directly followed by input without an intervening call to the fflush function or to a file positioning function (fseek, fsetpos, or rewind), and input shall not By the way, errno is not always a variable.

If there is no EOF, you must use an intervening call to a file-positioning function. If the file already exists, the fopen() call will fail by returning FALSE and generating an error of level E_WARNING. This is equivalent to specifying O_EXCL|O_CREAT flags for the underlying open(2) system call. 'x+' Create and open for reading and writing; otherwise it has the same behavior as 'x'.
