This function is missing on some platforms:
|
|
mingw, MSVC 14, BeOS.
|

@item

Attempts to @code{shmat} into a previously malloc-ed region fail on SunOS 4,
|
|
with @code{errno} set to @code{EINVAL}, even if there is an @code{munmap} call
|
|
in between.
|
|
@item
|
|
On Linux, the flag @code{SHM_REMAP} is needed in order to force @code{shmat}
|
|
to replace existing memory mappings in the specify address range. On other
|
|
platforms, it is not needed.
