◆ v18_free()
Release a V.18 context.
Free a V.18 context.
- Parameters
-
- Returns
- 0 for OK.
References queue_release().
◆ v18_get_current_mode()
Get the current mode of a V.18 connection.
- Parameters
-
- Returns
- The mode.
◆ v18_init()
Initialise a V.18 context.
Initialise a V.18 context.
- Parameters
-
s | The V.18 context. |
calling_party | True if caller mode, else answerer mode. |
mode | Mode of operation. |
nation | National variant for automoding. |
put_msg | A callback routine called to deliver the received text to the application. |
user_data | An opaque pointer for the callback routine. |
- Returns
- A pointer to the V.18 context, or NULL if there was a problem.
◆ v18_mode_to_str()
const char * v18_mode_to_str |
( |
int |
mode | ) |
|
Return a short name for an V.18 mode.
- Parameters
-
mode | The code for the V.18 mode. |
- Returns
- A pointer to the name.

) |
| |
Put a string to a V.18 context's input buffer.
- Parameters
-
s | The V.18 context. |
msg | The string to be added. |
len | The length of the string. If negative, the string is assumed to be a NULL terminated string. |
- Returns
- The number of characters actually added. This may be less than the length of the digit string, if the buffer fills up. If the string is invalid, this function will return -1.
