And? Do you have a question?

[Lost User]

You should not use fprintf to write binary data (.wav files); use WriteFile as I suggested in my previous post. You can use fprintf to create a text file containing the names of all your files.

Your program could simply write its output to console (e.g. using printf function, or cout object), then (on program invocation) you may redirect the standard output to a text file, e.g.

myprogram > myfile.txt

THESE PEOPLE REALLY BOTHER ME!! How can they know what you should do without knowing what you want done?!?! -- C++ FQA Lite

[mybm1]

do this WriteFile function work in ubuntu ?

[mybm1]

Actually without giving command I want to generate itself..that why but Thanks anyhow..

[Lost User]

My apologies, you need fwrite[^] in Linux.

[mybm1]

By the way how to use this function?

[CPallini]

There is the documentation for the very purpose of learning function (or object) usage: Basic Input/Output at C++ reference[^]. printf at C++ reference[^].
