I'm using C++ to read some chars from a file and store them in a buffer, however, I'm witnessing strange behavior with ifstream's read function.
To start with, I'm using this code snippet to get the file's length:
input.seekg (0, input.end);
int length = input.tellg();
input.seekg (0, input.beg);
After that, I call read() to get length bytes from the file.
It works fine, except for one thing: If I use input.gcount() to see how many bytes were read, this number is much less that the length of the file we got above (but shows the actual nuber of bytes in the file).
Do you guys know anything about the difference between the file's length, found by using tellg(), and the number of bytes read afterwards, as reported by gcount()?
Sorry for any formatting issues (I'm using my phone).
Thanks a lot.
Edit :
That's the code (more or less) I'm using:
ifstream input("test.txt");
input.seekg (0, input.end);
int length = input.tellg();
input.seekg (0, input.beg);
input.read(buffer,length);
int extracted = input.gcount();
