What is sizeof(std::streamsize) ?

[mathieu]

Hi,

I was trying to work around the #define _LARGEFILE_SOURCE/
_FILE_OFFSET_BITS... nightmare to get large file support in C,
thinking that things were nicely done in C++. But at least on my
compiler the size of std::streamsize is 4 !
How am I supposed to deal with large file in this case ?

Thanks,
-Mathieu
Ps: for some reason a google search did not reveal anything
interesting...

Use the nativce operating system API.

Use the nativce operating system API.

$ wc boost_1_34_1/libs/filesystem/src/operations.cpp
1298 5115 46354 boost_1_34_1/libs/filesystem/src/operations.cpp

Great... all I wanted was simply the file size of a file...
