I have basic idea about malloc and calloc

i heard about falloc and dlmalloc, can any one explain about it?

non-standard functions. google and you will find out how to use them.

what do you meant by non-standard function?
falloc is far mallaoc . but i fot only that idea.
Thank you for your reply

I mean that they are not part of the standard C or C++ libraries. Standard functions are defied by the c and c++ ISO standards committee and every c or c++ compiler must implement them. You will find lists of standard functions in most text books related to c and/or c++ languages. Anything not identified as standard is, by its very definition, non-standard.
