ibdev
Name
ibdev -- open a device (device)
Synopsis
int ibdev(int board_index, int pad, int sad, int timeout, int send_eoi, int eos);
Description
ibdev() is used to obtain a device descriptor, which can then be used by
other functions in the library. The argument board_index
specifies which GPIB interface board the device is connected to.
The pad and sad arguments specify
the GPIB address of the device to be opened (see ibpad() and ibsad()).
The timeout for io operations is specified by timeout
(see ibtmo()). If
send_eoi is nonzero, then the EOI
line will be asserted with the last byte sent during writes (see
ibeot()).
Finally, the eos
argument specifies the end-of-string character and whether or not its
reception should terminate reads (see ibeos()).
Return value
If sucessful, returns a (non-negative) device descriptor. On failure, -1 is returned.
