[PATCHv2 16/60] bluetooth: Name BlueZ 4 symbols accordingly

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Jo?o Paulo Rechi Vita <jprvita@xxxxxxxxxxxxx>

We need diferent symbol prefixing for the current BlueZ 4 support and
the new BlueZ 5 support which is about to enter the codebase, to avoid
symbol clashing and crashing the daemon in the case both modules are
loaded at the same time.

This commit replaces all pa_bluetooth_ and pa_bt_ (for consistency)
prefixes with pa_bluez4_, for both lower-case and upper-case, what was
done with the following sed commands:

 $ sed -i s/pa_bluetooth_/pa_bluez4_/g src/modules/bluetooth/*bluez4*
 $ sed -i s/PA_BLUETOOTH_/PA_BLUEZ4_/g src/modules/bluetooth/*bluez4*
 $ sed -i s/pa_bt_/pa_bluez4_/g src/modules/bluetooth/*bluez4*
 $ sed -i s/PA_BT_/PA_BLUEZ4_/g src/modules/bluetooth/*bluez4*
