Nmap Malloc etc...

[lasek]

Hi all...now after a lot of experiments in c programming(two weeks..for
precision), i've seen another strange instraction..and i post you the
question...
Like in the subject...why i must use nmap rather then malloc????.
Best regards all..
See you from Rome, Cla.

What's nmap? Never heard of that function - it's definitely not
a standard C function. So there definitely does not seem to be
any need to use it instead of malloc() if you write portable C
programs. Should you mean "mmap()" instead of "malloc()", then
you're talking about a UNIX (only?) function that allows to map
a file into memory (but also allows to allocate a memory region
under certain conditions) and in that case you better ask that
question in e.g. comp.unix.programmer - but then tell a bit more
about the context, without it your question makes no sense even
if you should be talking about UNIX specific programs.

Sorry you say the true...i've a mistake to write the correct name of the
function, in effect is 'MMAP' and no 'nmap'..now i post in the correct
forum, thanks a lot.

...i've seen a file.pc and inside this, the programmer it used the function
mmap to store a struct with some particular flag permission..so my first
question was..i can use also malloc instead of mmap ? because my know-how
in C...is not enough sufficient...so i've more difficult to understand
mmap rather then malloc.
Thanks...

You are working on an ucLinux system and referrint to mmap()?

If yes... That's OS specific.

If not... That's weird. Choose another compiler.
