Current and Peak Memory consumption of my program?

Hi,

my C++ program does some memory consuming tasks and runs several minutes.
During execution time, I want to print information on the current memory consumption and peak memory consumption of my program into a logfile.
How can I retrieve this information, i.e. which functions are available to get memory and peak memory of my program?
I don't want to call any commands like "ps" etc. via system(), but would like to use functions supported by AIX and implement them in my C++ coding.

Thanks!

APACHE_CHILD_TERMINATE(3)						 1						 APACHE_CHILD_TERMINATE(3)

apache_child_terminate - Terminate apache process after this request

SYNOPSIS
bool apache_child_terminate (void ) DESCRIPTION
apache_child_terminate(3) will register the Apache process executing the current PHP request for termination once execution of PHP code is completed. It may be used to terminate a process after a script with high memory consumption has been run as memory will usually only be freed internally but not given back to the operating system. RETURN VALUES
Returns TRUE if PHP is running as an Apache 1 module, the Apache version is non-multithreaded, and the child_terminate PHP directive is enabled (disabled by default). If these conditions are not met, FALSE is returned and an error of level E_WARNING is generated. CHANGELOG
+--------+---------------------------------------------------+ |Version | | | | | | | Description | | | | +--------+---------------------------------------------------+ | 5.4.0 | | | | | | | This function became available under FastCGI. | | | Previously, it was supported only when PHP was | | | installed as an Apache module. | | | | +--------+---------------------------------------------------+ NOTES
Note This function is not implemented on Windows platforms. SEE ALSO
