5.4.2.2 sysFindPCIDevice

This function returns the location of PCI devices that have a specific Device ID and Vendor ID.

Given a Vendor ID, a Device ID, and an Index, the function returns the Bus Number, Device

Number, and Function Number of the Nth Device/Func tion whos e Vendor ID and Device ID match

the input parameters.

Calling software can find all devices having the same Vendor ID and Device ID by making

successive calls to this function starting with the index set to “0”, and incrementing the index until

the function returns DEVICE_NOT_FOUND. A return value of BAD_VENDOR_ID indicates that

the Vendor ID value passed had a value of all “1”s.

Calling convention:

int sysFindPCIDevice (

int de vice_id,

int vendor_id,

int inde x

);

Return values:

This function returns SUCCESSFUL if the indicated device is located, DEVICE_NOT_FOUND if

the indicated device cannot be located, or BAD_VENDOR_ID if the vendor_id value is illegal.

5.4.2.3 sysFindPCIClassCode

This function returns the location of PCI devices that have a specific Class Code. Given a Class

Code and an Index, the function returns the Bus Numbe r , Dev ice Number, and Function Number of

the Nth Device/Function whose Class Code matches the input parameters.

Calling software can find all devices having the same Class Code by making successive calls to

this function starting with the inde x set to “0”, and inc rementi ng t he inde x unt il t he func tion ret urns

DEVICE_NOT_FOUND.

Calling convention:

int sysFindPCIClassCode (

int class_code,

int index

);

Return values:

This function returns SUCCESSFUL when the indicated device is located, or

DEVICE_NOT_FOUND when the indicated device cannot be located.
