doubt regarding mmap() function call

[sam_cit]

Hi Everyone,

I searched for mmap() and i found the following in wikipedia,

'Anonymous mappings are mappings of physical RAM to virtual memory.
This is similar to malloc, and is used in some malloc implementations
for certain allocations'

I understood that the memory contents are mapped to files using
mmap()

However, from the following link,

http://ou800doc.caldera.com/en/man/html.2/mmap.2.html

I understand that mmap() just avoids read/write concept of a file and
makes sure that files are accessed as raw memory.

Can anyone help me as to what is correct about mmap()?

Thanks in advance!!!

Try comp.unix.programmer or your man pages, mmap() is off topic here.
