+1  Q: 

"blkclr (mach_kernel)" shows up in mac's shark profiler. What does it do?

I am profiling a C program using Mac's Shark which shows that some of CPU time goes to "blkclr" in "mach_kernel". What does this kernel function do? I speculate it is related to memory allocation, but I am not sure. I have googled for some time, but could not find the answer, either. Does someone know this? Thanks in advance.

Zeroes out a block of memory

Thanks, NSD. This is exactly what I want. Actually I should try code search first before asking the question.
