Does an index have a currency? Return Value If the file is successfully opened, the function returns a pointer to a FILE object that can be used to identify the stream on future operations. The stream is fully buffered unless filename refers to an interactive device.

mode is used to determine the file access mode. 2) Same as (1), except that the pointer to the file stream is written to streamptr and the following errors are detected File access mode flag "x" can optionally be appended to "w" or "w+" specifiers.

On most library implementations, the errno variable is also set to a system-specific error code on failure. Not a member yet? To check for errors, you need to Set errno to 0 before the call; Make the call and check the value it returned to see whether it succeeded or failed; and http://jamisonsoftware.com/error-code/ftp-return-code-10000-error-code-00010.php This flag has effect only on Windows systems.
Not the answer you're looking for? Fopen_s Gcc a+ Open for reading and appending (writing at end of file). This is strictly for compatibility with C89 and has no effect; the 'b' is ignored on all POSIX conforming systems, including Linux. (Other systems may treat text files and binary files
Yes No Additional feedback? 1500 characters remaining Submit Skip this Thank you! In addition to the above characters, fopen() and freopen() support the following syntax in mode: ,ccs=string The given string is taken as the name of a coded character set and the A bullet shot into a door vs. _wfopen_s Example I suspect the path you're specifying in your code is wrong.
The file pointer can be repositioned by using fseek or rewind, but it's always moved back to the end of the file before any write operation is carried out so that If there is no EOF, you must use an intervening call to a file-positioning function. Opening a file in append mode (a as the first character of mode) causes all subsequent write operations to this stream to occur at end-of-file, as if preceded the call: fseek(stream, http://jamisonsoftware.com/error-code/ftp-return-code-10000-error-code-00009.php Assuming you're on a Windows system, opening "C:\\List.txt" for output shouldn't fail with errno==2, which means "No such file or directory". (You are on Windows, right?
Especially you. A component of a specified pathname did not exist, or the pathname was an empty string. Thanks. To open a new or existing Unicode file, pass a ccs flag that specifies the desired encoding to fopen_s:fopen_s(&fp, "newfile.txt", "rw, ccs=encoding");Allowed values of encoding are UNICODE, UTF-8, and UTF-16LE.
You'd have to revise your code to explicitly test dfile before I'd be willing to believe your assertion that dfile is null (and report the error on a channel other than 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. To verify why fopen() fails, do as I suggested with errno. With modern technology, is it possible to permanently stay in sunlight, without going into space?
The mode of the stream (one of the values "r", "r+", "w", "w+", "a", "a+") must be compatible with the mode of the file descriptor. You don't know that the call failed, because you didn't check whether dfile == NULL. The operations that are allowed on the stream and how these are performed are defined by the mode parameter. Insults are not welcome.
e (since glibc 2.7) Open the file with the O_CLOEXEC flag. If the file exists, its contents are destroyed."a+"Opens for reading and appending. BUGS top When parsing for individual flag characters in mode (i.e., the characters preceding the "ccs" specification), the glibc implementation of fopen() and freopen() limits the number The "a+" mode does remove the EOF marker before appending to the file.
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 A description of the project, information about reporting bugs, and the latest version of this page, can be found at https://www.kernel.org/doc/man-pages/.
