Subject: How does malloc tell the kernel to allocate more memory?
Date: Sun, 8 Dec 2002 12:46:57 -0600	[thread overview]
Message-ID: <000301c29eea$3107dd10$032a1c43@joe> (raw)

I'm trying to write a tracer on memory allocation, and I'm having a little
trouble figuring this out.

At some point, malloc has to call the kernel to tell it to allocate more
memory for this user process, right?  I can't figure out which function
malloc calls, or where in the code (line number) it's called.

I'm looking at glib-2.3.1 to try and find my answers.  After all, that's
where malloc is defined, right?

TIA.

Joseph Wagner
