Hi,
That seems reasonable, but I can only find UIO_MAXIOV referenced
in 5 files and defined in 1. Thus, I was thinking about simply
updating those references, but still leaving UIO_MAXIOV defined,
though depricated.
If the above is simply not the direction we want to go, then
I beleive that UIO_MAXIOV should atleast be defined in terms
of IOV_MAX in sys/uio.h:
#include <limits.h> # bring in IOV_MAX
#ifdef _KERNEL
#define UIO_MAXIOV IOV_MAX
#endif
Question: does anyone know the appropriate #define to use
for IEEE Std. 1003.1-200x, or should _SC_IOV_MAX
simply be put behind the non-expansion controlled
comment (in /usr/src/lib/libc/gen/sysconf.c)
switch (name) {
/* 1003.1 */
Comments?
Thanks,
-John
