>Description:
I am trying to open a tape device for reading(or writting doesn't seem
to matter), if I link with the normal C library everything works great.
If I link with libc_r I get a "inappropriate ioctl for device mesage".
I am using a K6, with 64MB of memory, a Buslogic BT948 SCSI card, and
a Seagate STT8000N tape drive. Everything on the machine is straight off
the CD.
>How-To-Repeat:
The following program demonstrates the bug everytime, here is how I'm
compiling and running it.
% cc -DREENTRANT bug.c
% ./a.out
% cc -DREENTRANT bug.c -lc_r
% ./a.out
Open:: Inappropriate ioctl for device
And here is the source:
#include <stdio.h>
#include <errno.h>
#include <fcntl.h>
int main (void){
int handle;
handle=open("/dev/nrst0",O_RDWR);
if(handle == -1){
perror("Open:");
return(1);
}else{
close(handle);
}
}
>Fix:
I don't have a fix for it at this time.
