You guys shouldn't be counting bytes. Use the sizeof() operator the C compiler will tell you how big the structure is.
I'm not writing C code but euphoria binding to termios, so sizeof() is of no use to me. Anyway there is not padding as when I peek the struct all members are at expected position here the code:
function peek_termios(atom pTermios) return peek4u({pTermios,4}) & peek(pTermios+16) & {peek({pTermios+17,NCCS})} & peek4u({pTermios+17+NCCS,2}) end function
the extra byte is at end of allocated struct. Matt code give this on Linpus lite compiled with gcc 4.1.2
termios2: 44 c_iflag: 0xbfc9e408 c_oflag: 0xbfc9e40c c_cflag: 0xbfc9e410 c_lflag: 0xbfc9e414 c_line: 0xbfc9e418 c_cc: 0xbfc9e419 c_ispeed: 0xbfc9e42c c_ospeed: 0xbfc9e430So there is no padding between fields but allocationg 44 crash my program. Well I will take it as a mystery and go on with TERMIOS_SIZE=45
