Decoded Buffer Bytes Writing On Disk

[mubx2000]

Hi,

I want A code that Recive downloaded file Inside email message and Decoding it (e.g.Base64) Lets say the Decoding Method Is Here:

TInt CMimeCodeBase64::Decode(TDesC& pbOutput, TInt nMaxSize)

If The User Set (100)Kb for (nMaxSize) and the Size of The (Downloaded) file Is (500) that Means Every (100)K five times I will Recieve a Buffer for writing on the Disk Every time I will Recive 100K decoded then Write it to a disk ...etc, I want a code that do this process How I write this Code?

Note : I dont want you to Write a code for Decoding (Routine) Inside the method (Decode) Consider It is written and ready for use.
