dladdr for AIX 5.3
Hi,
Am new to AIX and am trying to find a function that works similar to the function dladdr on HP-UX which takes parameter as an address and a Dl_info type.

On AIX am finding it hard to get a function that does the same job as dladdr does.

Basically what I am doing is getting an address from _builtin_return_address and then pass this as one of the parameters to dladdr and the other as a Dl_info type.

The Dl_info type has 4 elements

function name
file name
nearest object
and one more such thing (sorry since i dont use this one I dont remember it at the moment :|)
This way I am able to trace a function call (a malloc call) on HP UX.
Now there is a dl_info on aix but it does not seem to serve the same purpose.

Could some one please guide me as to how I could do the same on AIX as I have done on HP UX.

1)to find somethign similar to Dl_info(on hp ux) in AIX
2)to find somethign similar to dladdr(on hp-ux) in AIX
Thank you very much in advance Smilie

dladdr

DLADDR(3)						   BSD Library Functions Manual 						 DLADDR(3)

NAME

     dladdr -- find the image containing a given address

SYNOPSIS

     #include <dlfcn.h>

     int
     dladdr(const void* addr, Dl_info* info);

DESCRIPTION

     The dladdr() function queries dyld (the dynamic linker) for information about the image containing the address addr.  The information is
     returned in the structure specified by info.  The structure contains at least the following members:

     const char* dli_fname     The pathname of the shared object containing the address.

     void* dli_fbase	       The base address (mach_header) at which the image is mapped into the address space of the calling process.

     const char* dli_sname     The name of the nearest run-time symbol with a value less than or equal to addr.

     void* dli_saddr	       The value of the symbol returned in dli_sname.

     The dladdr() function is available only in dynamically linked programs.

ERRORS

     If an image containing addr cannot be found, dladdr() returns 0.  On success, a non-zero value is returned.

     If the image containing addr is found, but no nearest symbol was found, the dli_sname and dli_saddr fields are set to NULL.

SEE ALSO

     dyld(3), dlopen(3)

HISTORY

     The dladdr() function first appeared in the Solaris operating system.

AUTHORS

     Mac OS X 10.3 incorporated the dlcompat package written by Jorge Acereda <jacereda@users.sourceforge.net> and Peter O'Gorman <ogor-
     man@users.sourceforge.net>.

     In Mac OS X 10.4, dlopen was rewritten to be a native part of dyld.

     This man page was borrowed from FreeBSD and modified.

BUGS

     This implementation is almost bug-compatible with the Solaris implementation.  The following bugs are present:

     o	 Returning 0 as an indication of failure goes against long-standing Unix tradition.
