Possible errors when creating a map.

Variants

ErrFdNotAvail	The following are POSIX-specific fd was not open for reading or, if using MapWritable, was not open for writing.
ErrInvalidFd	fd was not valid
ErrUnaligned	Either the address given by MapAddr or offset given by MapOffset was not a multiple of MemoryMap::granularity (unaligned to page size).
ErrNoMapSupport	With MapFd, the fd does not support mapping.
ErrNoMem	If using MapAddr, the address + min_len was outside of the process's address space. If using MapFd, the target of the fd didn't have enough resources to fulfill the request.
ErrZeroLength	A zero-length map was requested. This is invalid according to POSIX. Not all platforms obey this, but this wrapper does.
ErrUnknown	Unrecognized error. The inner value is the unrecognized errno.
ErrUnsupProt	The following are Windows-specific Unsupported combination of protection flags (MapReadable/MapWritable/MapExecutable).
ErrUnsupOffset	When using MapFd, MapOffset was given (Windows does not support this at all)
ErrAlreadyExists	When using MapFd, there was already a mapping to the file.
ErrVirtualAlloc	Unrecognized error from VirtualAlloc. The inner value is the return value of GetLastError.
ErrCreateFileMappingW	Unrecognized error from CreateFileMapping. The inner value is the return value of GetLastError.
ErrMapViewOfFile	Unrecognized error from MapViewOfFile. The inner value is the return value of GetLastError.
