Expand description
\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 device - Device to get identifier string for
