Buffer Creation

[Mugdha]

Which system calls are used to create a buffer in linux........

i m searching for functions similar to
getbuffer()
freebuffer()
getbufferID()

etc in linux

This buffer is to be shared by multiple threads.
how do i proceed?

A buffer is anything that stores data and can be accessed with an index. I never understood why people use strange stuff which will cause portability problems.

Why not just use an array (if it's of a fixed size) or malloc/realloc if you need to dynamically size it? Anyway, if you love those names or something, you can wrap malloc into functions with those names if you need a more specific behavior.

i92guboj, I don't think that Mugdha wants to use any sort of strange stuff. I think he's just new here, and wants to know how we normally do things. :)

Mugdha, i92guboj is correct. Use the functions malloc() and (if you need it) realloc() for your memory needs. Use free() to free memory you no longer need.

For information on how these functions work, enter each of these commands at the command line:

man -a malloc
man -a realloc
man -a free

If man pages are not installed on your system, google for each of these:

man malloc linux
man realloc linux
man free linux

Hope this helps.

Sorry, I did not want to imply that. It was a generic comment that wasn't aimed directly at him. That was not my intention at all.
