Notes
The default implementation of Close()
is called every time
a file that is currently Open()
is no longer required.
Typically, the handle that was returned for the Open()
call is used to free
up the resource.
Your implementation must correctly report any system errors that might occur during the close.
Example
To use Close()
to close an
open file:
FileSys *f = FileSys::Create( FST_ATEXT ); Error e; f->Set( "c:\\configfile.txt" ); f->Open( FOM_WRITE, &e ); f->Close( &e );
To reimplement Close()
to
report errors using Error::Sys()
and provide
debugging output:
void FileSysDemo::Close( Error *e ) { if ( close( fd ) == -1 ) e->Sys( "close", Name() ); if ( DEBUG ) printf( "Debug (Close): %s\n", Name() ); }
