addr must be aligned to a page boundary. The function mprotect () specifies the desired protection for the memory page (s) containing part or all of the interval [ addr, addr + len -1]. If an access is disallowed by the protection given it, the program receives a SIGSEGV. prot is a bitwise-or of the following values: The new protection replaces any existing protection. mprotect () is not a standard C function; try comp.unix.programmer.

Now take the vma merging code out of mprotect.c and let it rely on vma_merge too: so vma_merge becomes the sole vma merging engine. The fruit of this consolidation is that mprotect now merges file-backed vmas naturally.

5 Nov 2013 Well known compilers like gcc and clang translate C/C++ source code so it's suitable for calling mprotect.
