calling glibc mallinfo() from GDB after attaching to a process?

[Chris Markle]

Hi,

I would like to attach to a running program, issue a call to the glibc 
mallinfo() function, display the returned mallinfo structure, and the 
continue execution of the program. The idea here is to grab some malloc 
statistics from a running program... Is this kind of thing possible? If 
so, can someone offer up some clues as to the GDB commands to issue to 
do this?
