ulimit

Hi,

 I  had written a program for memory stress testing which uses malloc
to allocate memory  in Mac OS.

 And i set ulimit for virtual memory, data segment and maximum
resident set size to 2048. But evenafter this i am able to allocate
more than 2048 kb.

can anyone help to findout why its so. This program fails to allocate
memory in Linux OS.

thanks in advance.
