How do I check for EOF in Python? I found a bug in my code where the last block of text after the separator isn't added to the return list. Or maybe there's a better way of expressing this function? Here's my code: def get_text_blocks(filename): text_blocks = [] text_block = StringIO.StringIO() with open(filename, 'r') as f...
so i have the following code opening an input stream and collecting the information successfully: httpInput = httpConnection.openInputStream(); sb= new StringBuffer(); while (ch != -1) { ch = httpInput.read(); sb.append(...
So I have a bit of problem figuring what Perl does in the following case: while(1){ $inputLine=<STDIN> #parse $inputLine below #BUT FIRST, I need to check if $inputLine = EOF } before I get the obvious answer of using while(<>){}, let me say that there is a very strong reason that I have to do the above (basically setting up an alar...
My python program has two calls to raw_input() The first raw_input() is to take multiline input from the user. The user can issue Ctrl+D (Ctrl+Z in windows) for the end of input. Second raw_input() should take another input from user with (y/n) type prompt. Unfortunately (in Mac OS X only?), second raw_input() raises EOFError when th...
Hello, I am writing a destop script on windows 2003 and I need to open a file and seek to the end of it and read the last line. I looked for a "seek" but couldn't find. I saw the openTextFile for option but didn't have. I implement it by openning the file with the red flag and then reading line after line. With big file it takes a ti...

I'm doing a hw assignment and my professor uses this code to test our program: int main() { const int SZ1 = 10; const int SZ2 = 7; const int SZ3 = 5; float array1[SZ1]; float array2[SZ2]; float array3[SZ3]; DisplayValues(SortValues(GetValues(array1, SZ1), SZ1), SZ1); DisplayValues(SortValues(GetValues(array2, SZ...
I have a small shell that creates children (with fork()) and make them execute some commands with execvp. It support also the & option so the father can run other commands in the meanwhile. When a child die i want to write that on the console and also the child pid, so i defined a sighandler for SIGCHLD: void backdeadchild(int sig) { i...
I was using the form used in one of the related questions. Only problem is that i keep getting right at the end of the file. The file is an fstream and the str is a string. Unhandled exception Microsoft C++ exception: std::ios_base::failure while (getline(file, str)) { } if (cin.bad()) { // IO error } else if (!cin.eof()) ...
Is there an easy way to check if a file is empty. Like if you are passing a file to a function and you realize it's empty, then you close it right away? Thanks. Edit, I tried using the fseek method, but I get an error saying 'cannot convert ifstream to FILE *'. My function's parameter is myFunction(ifstream &inFile) ...
Hi, When I use file functions in PHP, I check for EOF. I wonder if EOF actually exist in a file. When I create an empty text file, it displays 0KB. How does EOF exist in a file with 0KB? ...

I would like to execute some program through ssh and redirect its input from a file. The behaviour of the following code: channel.exec_command('cat') with open('mumu', 'r') as f: text = f.read() nbytes = 0 while nbytes < len(text): sent = channel.send(text[nbytes:]) if sent == 0: break nby...
I've got some code executing in a while(fscanf != EOF) loop. However, even when fscanf has finished executing, I need to keep running that code until some conditions are met. I mean I guess I could copy/paste the code to outside the while(fscanf) loop, and only use global variables, but that seems messy. Surely someone has encountered so...
Hello, I have a structure in my program that contains a particular array. I want to scan a random file with numbers and put the contents into that array. This is my code : ( NOTE : This is a sample from a bigger program, so I need the structure and arrays as declared ) The contents of the file are basically : 5 4 3 2 5 3 4 2 #include...
Most of the languages like C++ when writing into a file, put an EOF character even if we miss to write statements like : filestream.close However is there any way, we can put the EOF character according to our requirement, in C++, for an instance. Or any other method we may use apart from using the functions provided in C++. If you ne...
According to the man page for read(2), it only returns zero when EOF is reached. However, It appears this is incorrect and that it may sometimes return zero, perhaps because the file is not ready to be read yet? Should I call select() to see if it is ready before reading a file from disk? Note that nBytes is: 1,445,888 Some sample co...
Hello, I'm using a DataReader to display informations stored in a table. I created Two button to go to next record and to go back. In VB6 I used this code : While Not Recordset1.EOF Recordset1.MoveNext End While In ASP.NET I didn't find a way to do like it, because DataReader hasn't the EOF property. EDIT : While Not Recordset1.B...

If I send well formatted XML, I get an error message: Server Exception: Cannot access a closed Stream If the XML isn't well formatted, I get HTTP 500.
