I was thinking about this when I ran into a problem using std::ofstream. My thinking is that since std::ifstream, it wouldn't support random access. Rather, it would just start at the beginning and stream by until you get to the part you want. Is this just quick so we don't notice? And I'm pretty sure FILE* supports random access so th...
Hi all, Is there a way to directly read a binary file into RAM? What I mean is, is there a way to tell the compiler, here's the file, here's the block of RAM, please put the file contents in the RAM, off you go, quickly as you can please. Currently I'm stepping through the file with ifstream loading it into RAM (an array) 64bit block ...
Can anyone explain the following behaviour to a relative newbie... const char cInputFilenameAndPath[] = "W:\\testerfile.bin"; int filesize = 4584; char * fileinrampointer; fileinrampointer = (char*) malloc(filesize); ifstream fsInputFileStream; fsInputFileStream.open(cInputFilenameAndPath, fstream::in | fstream::binary); fsInputFileS...
I'm working on a file format that should be written and read in several different operating systems and computers. Some of those computers should be x86 machines, others x86-64. Some other processors may exist, but I'm not concerned about them yet. This file format should contain several numbers that would be read like this: struct Lon...
Hello All, I am pretty new to socket programming. I have a function call similar to: len = read(FD, buf, 1500); [which is responsible for reading data from a telnet connection] a printf in the next line shows buf to be >300 characters in length but (int)len gives only 89! Because of this all further parsing of the returned string fa...
If I call read() on a DataInputStream, will it take up CPU cycles waiting for data or does it yield the current thread and get woken up by an interrupt signaling that data has arrived? My motivation for asking the question is to determine whether or not a stream reader needs to be in its own thread or not. A blocking read that takes up...

I have a C++ File class with read function, that is supposed to read whole contents of a file (just like Python does) into a buffer. However, when I tried to call read function from unistd.h, I get: file.cpp:21: error: no matching function for call to ‘File::read(int&, char*&, int)’ file.cpp:17: note: candidates are: char* File...

I have a child process which generates some output of variable length and then sends it to the parent using a half duplex pipe. In the parent, how do I use the read() function? Since the data can be of different length each time, how can I at run time know the size of the data to do any malloc() for a buffer? Can the fstat() function be ...

I've been evaluating large key-value stores recently and I keep coming acrosss the term 'read-repair' but have no clue what they are talking about. I think it has something to do with transactions but am not sure. Could someone please explain what it is and how it is different from the way traditional databases work? Maybe provide some ...

I have custom sections defined, but I've commented them out until I get the basics working. In web.config, I have this: <appSettings> <add key="buffer" value="65536"/> <add key="updateI...
I have a 2 MB file, not too large, that I'd like to put into an sqlite database so that I can search it. There are about 30K entries that are in CSV format, with six fields per line. My understanding is that sqlite on the iPhone can handle a database of this size. I have taken a few approaches but they have all been slow > 30 s. I've...
Trying to understand how you're supposed to read files in python. This is what I've done and it isn't working quite properly: import os.path filename = "A 180 mb large file.data" size = os.path.getsize(filename) f = open(filename, "r") contents = f.read() f.close() print "The real filesize is", size print "The read filesize is", len(...
