[comp.sys.encore] dread & dwrite system calls

ejd@goanna.cs.rmit.oz.au (Erick Delios) (06/10/90)

The program 'xx.c' listed below produces the following errors during
compilation.  Is something missing from Umax 4.3 (R4.0.0) ?


undefined			first referenced
 symbol  			    in file
SYS_dread                           /lib/libc.a[dread.o]
SYS_dwrite                          /lib/libc.a[dwrite.o]
ld fatal: Symbol referencing errors. No output written to a.out


----- Test program --------
#include <sys/file.h>
#define FILE "/tmp/xxx"
main() 
{
int fp, a, r;

fp = open(FILE,O_RDWR);
r = dread(fp,(char *) &a,sizeof (int),0x100);
r = dwrite(fp,(char *)&a,sizeof (int),0x100);
}
---- End Test -----------------
