Prosody generic: API: sm_get_card_switch_ix

This function is only in Prosody before the V6 API.

Prototype Definition

int sm_get_card_switch_ix(tSMCardId card)

Parameters

card

The card whose associated switch driver index is to be determined.

Description

Given a Prosody carrier card index, returns index of associated switch driver (for use in switch driver API calls such as sw_set_output).

Note the switch driver index can also be obtained from sm_channel_info().

Returns

Switch driver index number if call completed successfully, otherwise a standard error such as:

• ERR_SM_BAD_PARAMETER - no card with specified card index
• ERR_SM_NO_ASSOCIATED_SWITCH - no associated switch driver
