A routine is available to display the results of a BT on a screen or a printer
or write formatted results to an ASCII file.
bt_print
format a BT queue entry for display. This function translates the
command, address (rack, group, slot), and status to English for writing to
screen or file, and formats the data as hex words, 8 per line.
Calling sequence:
bt_print(
fileptr, command, address, &qbtptr );
Arguments:
fileptr: stdout or stderr for screen output, or a pointer to a user file
opened with fopen.
command: an integer, either C_BT_READ or C_BT_WRITE.
address: the module address that was passed to the original queueing
function.
qbtptr: a pointer to your QBT type packet.
Returned values:
none.
Example: This code tests a BT for completion and prints the results when
the BT has finished:
#define OUT_VOLTS (16*4) /* rack 4 slot 0 */
static QBT btw;
. . .
bt_write(OUT_VOLTS, &btw);
. . .
if ( bt_done(&btw) )
bt_print(stdprt, C_BT_WRITE, OUT_VOLTS, &btw);
