Will the following code work ?
fd = socket(blah);
connect(fd, blah);
dup2(fd, STDIN_FILENO);
fp = fopen(fd, "a+");
fputc('x', fp);
close(STDIN_FILENO);
open("myfile", O_RDWR|O_APPEND); /* file contains data */
fseek(fp, 0, SEEK_SET);
fputs("hello world\n", fp);
or will it end up not attempting to seek to the end of the file and
overwriting from offset 0 ?
