Function cuDeviceGetPCIBusId

pub unsafe extern "C" fn cuDeviceGetPCIBusId(
    pciBusId: *mut c_char,
    len: c_int,
    dev: CUdevice,
) -> CUresult

\brief Returns a PCI Bus Id string for the device

Returns an ASCII string identifying the device \p dev in the NULL-terminated string pointed to by \p pciBusId. \p len specifies the maximum length of the string that may be returned.

\param pciBusId - Returned identifier string for the device in the following format [domain]:[bus]:[device].[function] where \p domain, \p bus, \p device, and \p function are all hexadecimal values. pciBusId should be large enough to store 13 characters including the NULL-terminator.

\param len - Maximum length of string to store in \p name

\param dev - Device to get identifier string for
