I'm trying to create a file on a SSD disk and map it for one-writer-many-reader applications, and to be able to make it safe I would like to divide the file into sectors/regions. So while the writer is writing data to its exclusively owned region, the readers can create views and reach the data from the part which is flagged let's say "available".
As soon as the writer inputs the new data, the "available" sector/region should include the newly added data as well for the reader applications.
The file size is known from the beginnig so no need for any kind of dynamic memory operation, but it will be big like over 55GB(it means it is too big to map all the file at one time). The data writing is pretty fast like 15 packages per second with each package size 1.5MB.
The OS will be Win 7 x64.
Is it possible to implement this kind of mechanism? I couldn't find any example, tutorial or any kind of document on internet, they just give simple examples like creating a file and creating a view etc... I need to know how to implement such pointer operations to divide the file into sectors and change the parts from "reserved"(for writing) and "available"(for reading). (I'm not very familiar with C++ language)
