Hi,
You could truss or tusc the process when you start the program.
In Solaris/HP-ux it goes like :
truss /program/to/start/myprog
When debugging an already running program you can do :
truss -p <processid>
There is one note :
AIX 5.1 has 'truss'.
AIX 4.3.3 and earlier you can use the 'trace' command - but it's a pain because it's a system-level trace from which you can then extract the information for the process you cared about.

sotruss
sotruss(1) User Commands sotruss(1)
NAME
sotruss - trace shared library procedure calls
SYNOPSIS
/usr/bin/sotruss [-f] [-F bindfromlist] [-T bindtolist]
[-o outputfile] executable [executable arguments...]
DESCRIPTION
sotruss executes the specified command and produces a trace of the library calls that it performs. Each line of the trace output reports
what bindings are occurring between dynamic objects as each procedure call is executed. sotruss traces all of the procedure calls that
occur between dynamic objects via the Procedure Linkage Table, so only those procedure calls which are bound via the Procedure Linkage Ta-
ble will be traced. See Linker and Libraries Guide
OPTIONS
-F bindfromlist A colon-separated list of libraries that are to be traced. Only calls from these libraries will be traced. The default
is to trace calls from the main executable only.
-T bindtolist A colon-separated list of libraries that are to be traced. Only calls to these libraries will be traced. The default is
to trace all calls.
-o outputfile sotruss output will be directed to the outputfile. If this option is combined with the -f option then the pid of the
executing program will be placed at the end of the filename. By default sotruss output is placed on stderr.
-f Follow all children created by fork() and print truss output on each child process. This option will also cause a
pid to be output on each truss output line.
EXAMPLES
Example 1 An example of sotruss.
A simple example shows the tracing of a simple ls command:
% sotruss ls | more
ls -> libc.so.1:*atexit(0xef7d7d1c, 0x23c00, 0x0)
ls -> libc.so.1:*atexit(0x1392c, 0xef7d7d1c, 0xef621bb0)
ls -> libc.so.1:*setlocale(0x6, 0x1396c, 0xef621ba8)
ls -> libc.so.1:*textdomain(0x13970, 0x1396c, 0xef621ba8)
ls -> libc.so.1:*time(0x0, 0xef61f6fc, 0xef621ba8)
ls -> libc.so.1:*isatty(0x1, 0xef61f6fc, 0x0)
ls -> libc.so.1:*getopt(0x1, 0xeffff8fc, 0x13980)
ls -> libc.so.1:*malloc(0x100, 0x0, 0x0)
ls -> libc.so.1:*malloc(0x9000, 0x0, 0x0)
ls -> libc.so.1:*lstat64(0x23ee8, 0xeffff7a0, 0x0)
...
ls -> libc.so.1:*printf(0x13a64, 0x26208, 0x23ef0)
ls -> libc.so.1:*printf(0x13a64, 0x26448, 0x23ef0)
ls -> libc.so.1:*exit(0x0, 0x24220, 0x2421c)
