We hit a problem in a code, and narrowed it down to a test case that does :
while (cnt) {
f=fopen(host_file, "a+");
if (!f)
perror("dup_host_file: Could not open hostfile");
/* rewind(f); */
while (cnt) {
int ret=fscanf(f, "%s", line);
if (ret != EOF) {
fprintf(f, "%s\n", line);
cnt--;
dup++;
}
}
fclose(f);
In earlier versions of cygwin we have, this works fine, however in the recently
installed
versions, it no longer works. It seems that fopen(host_file, "a+") is NOT
positioning the
read position at the start of the file as it should. Adding an explicit
rewind(f) is a
work around.
