I have a text file named num.txt who\'s only contents is the line 123. Then I have the following: void alt_reader(ifstream &file, char* line){
I\'m sure I\'ve just missed this in the manual, but how do you determine the size o开发者_JAVA技巧f a file (in bytes) using C++\'s istream class from the fstream header?You can open the file using the
Here\'s probably a very noobish question for you: How (if at all possible) can I return an ifstream from a function?
I wanted to know if it\'s possible to read a byte from a binary file with \"fstream\" and then change that byte and write it back.
I am doing tests on an ejb3-project using ejb3unit http://ejb3unit.sourceforge.net/Session-Bean.html for testing. All my Services long for @PersistenceContext (UnitName=bla). I set up the ejb3unit.pro
if i opened a file like: ofstream file(\"file.dat\",ios::binary); or开发者_开发知识库 ofstream file(\"file.dat\",ios::binary | ios::out);
I\'m trying to figure out the difference between opening a file like: fstream *fileName*(\"FILE.dat\",ios::binary);
ifstream::tellg() is returning -13 for a certain file. Basically, I wrote a utility that analyzes some source code; I open all files alphabetically, I start with \"Apple.cpp\" and it works perfectly.
I have this simple code that needs to get a chunk of a large log file that is being written into. At some point it stores the current location returned from
I am writing a function which should (if the file already exists) increment the first number by one and append the parameters of the function to the end of the file.
