Yes:
/* define if sys/ioctl.h exists */
#define HAVE_SYS_IOCTL_H 1
> Is the struct winsize definition guarded by #if/#ifdef?
Yes:
#ifdef _ALL_SOURCE
/* Common ioctl's for all disciplines which are handled in ttiocom */
enum tty_ioctl {
...
union txname { /* used with TXGETCD */
...
/*
* window size structure used with TXSETWIN and TXGETWIN. This is
* exactly the same as the Berkeley structure and can be used with
* TIOCSWINSZ and TIOCGWINSZ -- in fact they are defined to be the
* same.
*/
struct winsize {
unsigned short ws_row; /* rows, in characters */
unsigned short ws_col; /* columns, in characters */
unsigned short ws_xpixel; /* horizontal size, pixels */
unsigned short ws_ypixel; /* vertical size, pixels */
};
#endif /* _ALL_SOURCE */
So, I see only the #if/#ifdef which we want to avoid to use...
