Hello Bulat, Thursday, November 24, 2005, 4:17:24 AM, you wrote: BZ> but i propose to make these middle-level functions after stage 2 or BZ> even 3 in this scheme - so that they will be fully in Haskell world, BZ> only work with file descriptors instead of Handles. for example: "it's better one time to see, than 100 times to hear", so i attached my current Win32Files.hs to this letter. it's close to the FD library i propose, only open/seek functions need to be rewritten. of course, i will adapt this code to programming style used in the hierrachical libraries by implementing all the things i wrote in previous letter we will get i/o library, defined as stack of APIs: 1) c_* functions 2) FD API (and other Streams - memory buffer, String, socket, pipe, channel, mvar and so on) 3) Stream buffering API (Handle) 4) Char encoding for Handles API -- Best regards, Bulat mailto:bulatz@HotPOP.com
