What is the command for dumping memory segment information in Unix/Linux?

[waht]

Here is a small segment that was dumped after an error in a program has occurred - that does a lot of memory allocation.

b7ee6000-b7ee7000 rw-p 00157000 08:02 72280      /lib/libc-2.9.so             
b7ee7000-b7eea000 rw-p b7ee7000 00:00 0                                       
b7eea000-b7ef7000 r-xp 00000000 08:02 72115      /lib/libgcc_s.so.1           
b7ef7000-b7ef8000 r--p 0000c000 08:02 72115      /lib/libgcc_s.so.1           
b7ef8000-b7ef9000 rw-p 0000d000 08:02 72115      /lib/libgcc_s.so.1           
b7ef9000-b7f20000 r-xp 00000000 08:02 72284      /lib/libm-2.9.so             
b7f20000-b7f21000 r--p 00026000 08:02 72284      /lib/libm-2.9.so             
b7f21000-b7f22000 rw-p 00027000 08:02 72284      /lib/libm-2.9.so

Interestingly, it shows the privileges of different memory segments. I'm wondering if there is a command that dumps this kind information if you provide the start and stop memory address. Or to find out which segments are from the heap, or stack.

pmap will report the memory usage of a process

thanks, it works
