Description
Sample code:
we expect that filename exists
static void test_lseek(const char* filename)
{
int fd; = open(filename, O_RDONLY);
int rc;
struct stat st;
stat(filename, &st);
printf("size: %i\n", st.st_size); size: 0, for example
fd = open(filename, O_RDONLY);
rc = lseek(fd, 1000, SEEK_END);
printf("lseek result = %i\n", rc);
close(fd);
stat(filename, &st);
printf("size: %i\n", st.st_size); size: 1000 <-- BUG
}
- This can be reproduced for both FAT and IMFS.
Expected results: no grow for readonly files.
