Executing from a heap-allocated data area

[Rakesh Agarwal]

I am generating machine code on-the-fly into a "malloc"ed data area.  However, I get a segmentation fault when I transfer control to the data area.  I suspect this is caused by the fact that the data area has not been marked "executable".  Is there a Linux API that would allow me to make the area executable?   Thank you for you help.   Rakesh Agarwal
