 I am using latest version of Light Speed C and seem to have a problem
with fseek(). I am trying to do very simple thing (he-he-he):
FILE *inp;
long seek_value;

inp=fopen("some_name", "r");
/* check return code -- no problem */
/* some unrelated code */
seek_value=10; /* the file is much longer than 10 char */
fseek (inp, seek_value, 0);


at this point fseek returns negative value, I don't know why.
Moreover, if I open file as "r+" (which should not make any difference),
fseek returns 0, but does not seem to move the "file cursor" ( I tried ftell(..)
and it came back with 0.)
The same code runs with no problems on VAX or sun. The progam is just
read-file, write-file. No user interface to speak of.
Am I doing something wrong? IS this a known problem?
Any workarounds? Any suggestions? Please reply by mail.

Thank you in advance.
