It will append to it. :-) OTOH, it seems opening it for writing does
yield the exact same behaviour in FreeBSD.
You can try this with something like:
j@uriah 281% cat foo.c
#include <stdio.h>
int
main(void)
{
FILE *f;
f = fopen("/dev/stdout", "w");
fprintf(f, "Hello, world!\n");
return 0;
}
j@uriah 282% cc foo.c
j@uriah 283% ( echo "Goodbye world" ; ./a.out ) > foobar
j@uriah 284% cat foobar
Goodbye world
Hello, world!
The result is identical, regardless of whether "w" or "a" is used.
