npl::MatMap::MatMap ( std::string  filename, size_t  rows, size_t  cols  )

inline

Open an new file as a memory map. ANY OLD FILE WILL BE DELETED The file is always opened for writing and reading. Note the same file should not be simultaneously written two by two separate processes.

Parameters

filename	File to open
rows	Number of rows in matrix file
cols	number of columns in matrix file

npl::MatMap::MatMap ( std::string  filename, bool  writeable = false  )

inline

Open an existing file as a memory map. The file must already exist. If writeable is true then the file will be opened for reading and writing, by default write is off. Note the same file should not be simultaneously written two by two separate processes.

Parameters

filename	File to open
writeable	whether writing is allowed
