This post is related in some way to another post by you regarding the file descriptors. I don't know about any APIs that you can use, but you could just read the file one line at a time.
Also, according to the man page of /proc, in all kernels above 2.0, the last field in each line will contain the name of the file that is mapped to the particular region (if the second to last field is non-zero). So you can easily get the files that are mapped by that process. However, regarding create time of the library, file inodes in unix do not hold any information regarding file creation times, so you won't be able to get that.
Again, note that you will need root if you want to read this file for all processes on the system.

footprint
footprint(1) BSD General Commands Manual footprint(1)
NAME
footprint -- gathers memory information about a process or set of processes.
SYNOPSIS
footprint -h
footprint -proc <process-name> | -pid <pid> [-proc <process-name> | -pid <pid> [...]]
[-categories | -regions] [-swapped]
[-graphics] [-collapseSharing] [-targetChildren] [-skipIdleExitClean]
[-o <output-file-location>]
[-i <input-file-location>]
DESCRIPTION
footprint provides a summary number and a categorization that describe memory use that most impacts the system.
footprint gathers the sum of dirty/anonymous allocations in one or more processes along with their attributable kernel resources (currently
KPRVT). Shared allocations only contribute to the footprint once, regardless of the number of times that they are mapped into any number of
processes. The "footprint" value represents allocations that will cause the system to page in accommodation.
footprint needs to be run as root. It can target multiple processes via multiple instances of the -proc and -pid flags.
OPTIONS
-categories Detailed output on a per-VM-region type level (medium detail).
-regions Display all memory objects and associated regions that contribute to each category (high detail).
-swapped Display swapped bytes information where applicable.
-graphics Gather graphics data if available (platform dependent, not tallied into footprint total).
-collapseSharing Do not group shared memory output by process.
-targetChildren Gather footprint information for the set of processes launched directly or indirectly by the target processes.
-skipIdleExitClean Do not gather information on any processes that are ready to be quit on memory pressure. Also applicable after the fact
with -i option.
