LRN.C
This program uses a 2,000 element character array. To prevent stack
overflow errors when compiling and running this program using
Microsoft® QuickC©, change the stack size using the /F option of the
“qcl” command. An example of how this program might be compiled is:
qcl /AL /F 8192 b:\lrn.c c:\qc2\lib\clhpib.lib
/* LRN.C - This program queries the digitizer’s reset conditions */
/* Include the following header files */
#include <stdio.h>
#include <string.h>
#include <cfunc.h> /* This file is from the HP-IB Command Library Disk */
#define ADDR 70905L /* I/O path from PC to the digitizer, via the E1406 */
/****************************************************************************/
void main(void) /* Run the program */
{
char static *codes[] = {"*RST","*LRN?;*OPC?"};
char lrndata[2000], *prt, ch;
int loop,
length = 2000;
/* Execute each command group using a loop */
for (loop = 0; loop < (sizeof(codes) / sizeof(char*)); loop++ )
IOOUTPUTS( ADDR, codes[loop], strlen(codes[loop]));
