about virtual memory and memory leak

Hi,

First of all I appreciate this group very much for its informative discussions and posts.

Here is my question.

I have one process whose virtual memory size increases linearly from 6MB to 12MB in 20 minutes. Does that mean my process has memory leaks?

In what cases does the memory leak?. I just have preliminary idea that if you donot free the memory which is not in use, u have memory leak in ur program.

It would be really great if someone can post info about memory leak. Some link would do.

Thanks in advance,

-Ashish

NAME
_nc_freeall _nc_free_and_exit - curses memory-leak checking SYNOPSIS
#include <curses.h> void _nc_freeall(void); void _nc_free_and_exit(int); DESCRIPTION
These functions are used to simplify analysis of memory leaks in the ncurses library. They are normally not available; they must be con- figured into the library at build time using the --disable-leaks option. That compiles-in code that frees memory that normally would not be freed. Any implementation of curses must not free the memory associated with a screen, since (even after calling endwin), it must be available for use in the next call to refresh. There are also chunks of memory held for performance reasons. That makes it hard to analyze curses ap- plications for memory leaks. To work around this, one can build a debugging version of the ncurses library which frees those chunks which it can, and provides these functions to free all of the memory allocated by the ncurses library. The _nc_free_and_exit function is the preferred one since some of the memory which is freed may be required for the application to continue running. Its parameter is the code to pass to the exit routine. RETURN VALUE
These functions do not return a value. PORTABILITY
These functions are not part of the XSI interface. SEE ALSO
