It's not clear whether the program is attempting to determine it's own (or a child's) memory footprint, or that of an arbitrary process. In the former case, getrusage() is the obvious choice. This as a portable interface. If you want to examine arbitrary processes, the best interface on FreeBSD would be kvm_getprocs(3). BTW, since you mention heap objects, I presume you are aware that malloc() uses mmap(), rather than sbrk() to obtain memory. --=20 Peter Jeremy --3MwIy2ne0vdjdPXF Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) iEYEARECAAYFAk6hMN0ACgkQ/opHv/APuIeatQCglXjkBVAyxZ1bqGxU9gMHLthX 7noAoL4YBgGFaeg6b4HO8/SSpJI0AnHU =912H -----END PGP SIGNATURE----- --3MwIy2ne0vdjdPXF--
