Hello I seem to come up with a new question every day almost, but here goes! I have a structure as follows in my program : struct something { char ch; unsigned short int number; }; In Turbo-C the sizeof this struct is, as expected, 3 bytes. In DJGPP it is 4 bytes ???! The sizeof (char) and sizeof (unsigned short int) is 1 & 2 respectively in both compilers... Does DJGPP Word-align data, promoting the 3-byte strucure to 4 bytes? The reason I am asking is that I want to store many (60,000) such structs in an array, and wasting 60Kb+ in DJGPP seems crazy, even though memory is no problem. I want to avoid paging on small systems unless absolutely neccessary (sp?), so the extra 1 byte is irritating me... Thanks for an informative mailing list!
