#include <stdio.h>

main(argc,argv)
int argc
char *argv[];
{
int fd;
struct fildes fdbuf;
if (fd = open(argv[1],1) < 0) {
printf("Could not open %s \n",argv[1]);
exit(1);
}
_gs_gfd(fd,&fdbuf,sizeof(struct fildes));
printf("The file size is %ld \n",fdbuf.fd_fsize);
close(fd);
}
When I run this I do not get the file size any suggestions ?

If it opens the file successfully, then the fd will be set to "false", or 0. To have it parsed the way you want, try it this way instead: if ((fd = open(argv[1],1)) < 0) { ------------------------------------------------------------------------------- Steve Kirkendall kirkenda@cs.pdx.edu Grad student at Portland State U.

Oh.. Also... You need to put in: pflinit(); in the begining of main() before you print out floats or longs on the CoCo (Don't know about other OS9 machines)

Jeff, you forgot to put a pflinit(); in the source code. You have to do this in the OS-9 C compiler to bring in the printf long integer functions. -Bill- -- Bill Nobel - via FidoNet node 1:140/22 UUCP: ...!herald!weyr!Bill.Nobel Domain: Bill.Nobel@weyr.FIDONET.ORG Standard Disclaimers Apply...
