Function Documentation

char* pci_device_compute_udi (  HalDevice *  d, int  append_num )  [static]

This function will compute the device uid based on other properties of the device. Specifically, the following properties are required: pci.idVendor, pci.idProduct Other properties may also be used. Requirements for uid: do not rely on bus, port etc.; we want this id to be as unique for the device as we can make sure it doesn't rely on properties that cannot be obtained from the minimal information we can obtain on an unplug event Parameters: d  HalDevice object append_num  Number to append to name if not -1 Returns: New unique device id; only good until the next invocation of this function Definition at line 346 of file pci_bus_device.c.

void pci_ids_find (  int  vendor_id, int  product_id, int  subsys_vendor_id, int  subsys_product_id, char **  vendor_name, char **  product_name, char **  subsys_vendor_name, char **  subsys_product_name )  [static]

Find the names for a PCI device. The pointers returned are only valid until the next invocation of this function. Parameters: vendor_id  PCI vendor id or 0 if unknown product_id  PCI product id or 0 if unknown subsys_vendor_id  PCI subsystem vendor id or 0 if unknown subsys_product_id  PCI subsystem product id or 0 if unknown vendor_name  Set to pointer of result or #NULL product_name  Set to pointer of result or #NULL subsys_vendor_name  Set to pointer of result or #NULL subsys_product_name  Set to pointer of result or #NULL Definition at line 126 of file pci_bus_device.c. References pci_ids_line_iter_get_line(), pci_ids_line_iter_has_more(), pci_ids_line_iter_init(), and PCI_IDS_MAX_LINE_LEN.

dbus_bool_t pci_ids_free (   )  [static]

Free resources used by to store the PCI database. Parameters: #FALSE  if the PCI database wasn't loaded Definition at line 316 of file pci_bus_device.c. References pci_ids. Referenced by pci_device_shutdown().

char* pci_ids_line_iter_get_line (  unsigned int *  line_len  )  [static]

Get the next line from pci.ids. Parameters: line_len  Pointer to where number of bytes in line will be stored Returns: Pointer to the line; only valid until the next invocation of this function Definition at line 79 of file pci_bus_device.c. References pci_ids, pci_ids_iter_pos, pci_ids_len, and PCI_IDS_MAX_LINE_LEN. Referenced by pci_ids_find().

dbus_bool_t pci_ids_line_iter_has_more (   )  [static]

See if there are more lines to process in pci.ids. Returns: #TRUE iff there are more lines to process Definition at line 105 of file pci_bus_device.c. References pci_ids_iter_pos, and pci_ids_len. Referenced by pci_ids_find().

dbus_bool_t pci_ids_load (  const char *  path  )  [static]

Load the PCI database used for mapping vendor, product, subsys_vendor and subsys_product numbers into names. Parameters: path  Path of the pci.ids file, e.g. /usr/share/hwdata/pci.ids Returns: #TRUE if the file was succesfully loaded Definition at line 279 of file pci_bus_device.c. References DIE, pci_ids, and pci_ids_len. Referenced by pci_device_init().
