    max default buffer size in the write function

    Hi,

    Does anybody knows what is the max default buffer size in the write function?

    outfile.write (recvbuf, bytesRecv).

    I want to ckeck how many times this function will be called to write a big block data in a file.

    Thank you

    what's "outfile" - is it a ofstream? In that case, I don't think there is a technical limit - as long as there is enough memory, you can have it as large as the size element allows (e.g. 64KB or more on a 16-bit machine, 4GB on a 32-bit machine or many terabytes on a 64-bit machine).
