ibrdf -- read data bytes to file (board or device)
Synopsis
#include <gpib/ib.h>
int ibrdf(int ud, const char *file_path);
Description
ibrdf() is similar to ibrd()
except that the data bytes read are stored in a file instead
of an array in memory. file_path specifies
the save file. If the file already exists, the data will be appended
onto the end of the file.
