Description Daniel J Blueman 2003-03-11 09:24:44 EST

The man page for mremap(2) says to include these header files:
       #include <unistd.h>
       #include <sys/mman.h>

The flags argument can take the flag 'MREMAP_MAYMOVE' which is not defined in 
either of those files, but is in linux/mman.h.

See mremap(2) and grep /usr/include/sys/mman.h for MREMAP_MAYMOVE

Comment 1 Jakub Jelinek 2003-03-11 09:37:04 EST

MREMAP_MAYMOVE is a GNU extension, so you need to -D_GNU_SOURCE to get it,
otherwise it would break namespace of various standards.
See info libc on Feature Set Macros.
