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.

Constructor & Destructor Documentation

◆ ~proto_generic_file()

virtual libdar::proto_generic_file::~proto_generic_file ( )
inlinevirtualnoexcept

virtual destructor

Note
this let inherited destructor to be called even from a proto_generic_file pointer to an inherited class

Definition at line 74 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]ais where to put the data to read
[in]sizeis 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.
