ibwrtf -- write data bytes from file (board or device)
Synopsis
#include <gpib/ib.h>
int ibwrtf(int ud, const char *file_path);
Description
ibwrtf() is similar to ibwrt()
except that the data to be written is taken from a file instead
of an array in memory. file_path specifies
the file, which is written byte for byte onto the bus.
