Main consumer of this kind of interfaces (plural, SEEK_HOLE isn't the only one) are huge data applications, i.e. I know that Oracle, ADABAS, Sybase, DB2, Firebird, GoogleFS/MapReduce clones etc make use of sparse files and explicitly use this kind of interfaces if available to optimise performance. The problem of most interfaces for gathering the layout of holes is that they are proprietary or not portable and depend on a specific filesystem or platform. SEEK_HOLE solves at least this problem, and until now noone has proposed a better portable interface. _______________________________________________ ast-users mailing list [email protected] https://mailman.research.att.com/mailman/listinfo/ast-users
