directory size info and reconfiguration on a linux file system

Hi

I am new to Linux and have been trying to install and configure it on a machine. I currently have the following filesystem on Linux 2.4.21-37EL OS.

df -k /tmp

Filesystem 1k-Blocks Used Available Use% Mounted On
/dev/hda2 37341064 2006512 33437680 6% /

I need to ensure there is 400MB available on the tmp directory

when I perform a ls -la on / I get

drwxrwxrwx 13 root root 4096 Feb 9 11:11 tmp

what does the 4096 relate to?
are there any limitations on the amount of space that tmp can use? if so how do i determine what this is and how can i reconfigure it?

Thanks in advance

to the size of the directory entry itself. You may think of directory as of a special file, which has directory entries inside.

No. To limit that, You would need to put the /tmp on separate partition.

So the tmp or any other file on the filesystem can grow as large as the available space?

So why is there a directory entry size, what purpose does it server if the directory can grow to the size of the available space?
