2165
2166Calls the Linux-specific mremap(2) system call. The C<$scalar> must have
2167been mapped by C<IO::AIO::mmap>, and C<$flags> must currently either be
2168C<0> or C<IO::AIO::MREMAP_MAYMOVE>.
2169
2170Returns true if successful, and false otherwise. If the underlying mmapped
2171region has changed address, then the true value has the numerical value
2172C<1>, otherwise it has the numerical value C<0>:

2181C<IO::AIO::MREMAP_FIXED> and the C<$new_address> argument are currently
2182implemented, but not supported and might go away in a future version.

2184On systems where this call is not supported or is not emulated, this call
2185returns falls and sets C<$!> to C<ENOSYS>.
