Subject: questions about system function: mmap / fwrite
Date: Fri, 20 May 2005 11:14:47 +0200	[thread overview]
Message-ID: <d14685de050520021439e48c8d@mail.gmail.com> (raw)

Hello,

I have a question about ways of accessing a file. 

I know it is possible to use: fseek + fwrite/fread to access a file.
and It is also possible to map file in memory with  "mmap" function,
and access it by adressing memory.

Currently I use the frame buffer of  mobile phones with mmap function.
For my understanding, I would like to know what is the difference
between using fseek+fwrite compared to mmap style.
Dont hesitate to be precise or to use technical terms.

Thanks you,

Sylvanino
