Get the amount of memory allocated by malloc

Question

Is there an easy way to know the total amount of memory that has been allocated by every malloc in the program? I'm suffering from a memory leak and I want to find out where it is.

Answer 1

There is no way in a standard, operating system neutral, fashion.

But with GNU Glibc you have mallinfo

On Linux systems, you can learn about your virtual memory map thru the /proc/self/maps (or /proc/self/smaps which gives more details) pseudo-file. For process of pid 123 you can read /proc/123/maps

Of course, details are system specific.

To find a memory leak, use a tool like valgrind
