Here's the macro definition you cited upthread:
"""
From /usr/include/«arch»/bits/select.h on my Debian system:
#define __FD_ZERO(s) \
do { \
unsigned int __i; \
fd_set *__arr = (s); \
for (__i = 0; __i < sizeof (fd_set) / sizeof (__fd_mask); ++__i) \
__FDS_BITS (__arr)[__i] = 0; \
} while (0)
"""
Can you explain how that would cause a problem?
Note the following that precedes the macro definition in
/usr/include/x86_64-linux-gnu/bits/select.h on my Ubuntu system:
"""
#ifndef _SYS_SELECT_H
# error "Never use <bits/select.h> directly; include <sys/select.h> instead."
#endif
"""
so it's not going to be invoked from user-written code.
