[Linux-gpib-general] Problem with ibfind / ibask to get the minor number of controller

[Michael K <vk...@ya...>]

I have an interface defined in gpib.conf with ....
interface {    minor = 0                           board_type = "agilent_82357b"      name = "hp82357b"                 pad = 0                        sad = 0                       timeout = T30s                
/* settings for boards that lack plug-n-play capability */    base = 0    irq  = 0    dma  = 0
    master = yes}
If my program uses ibfind ....GPIBcontroller = ibfind( "hp82357b"  )

GPIBcontroller is returned as 16If I try to use ibask to get the minor number (needed to actually talk to a device on the controller)...
GPIBstatus = ibask(GPIBcontroller, IbaBNA, &boardIndex);

I get an error (4 - One or more arguments to the function call were invalid.) (status 0x8130).
What am I doing wrong ??Is there a better way to get the minor number from the interface name?
