## Detailed Description

ancestor class of generic_file

this class exist to avoid cyclic dependency between generic_file and infinint

Definition at line 54 of file proto_generic_file.hpp.

## Member Function Documentation

## read()

virtual U_I libdar::proto_generic_file::read | ( | char * | a,
|  | U_I | size
| ) |  |

pure virtual

read data from the proto_generic_file

Parameters

  [in,out] | a | is where to put the data to read
  [in] | size | is how much data to read

Returns
  the exact number of byte read.

Note
  read as much as requested data, unless EOF is met (only EOF can lead to reading less than requested data)
  EOF is met if read() returns less than size

Implemented in libdar::generic_file.

## write()

virtual void libdar::proto_generic_file::write | ( | const char * | a,
|  | U_I | size
| ) |  |

pure virtual

write data to the proto_generic_file

Note
  throws a exception if not all data could be written as expected

Implemented in libdar::generic_file.
