int | fax_release (fax_state_t *s) |
Release a FAX context. |
fax_state_t* fax_init | ( | fax_state_t * | s, | |
int | calling_party | |||
) |
Initialise a FAX context.
Initialise a FAX context.
s | The FAX context. | |
calling_party | TRUE if the context is for a calling party. FALSE if the context is for an answering party. |
int fax_release | ( | fax_state_t * | s | ) |
Release a FAX context.
Release a FAX context.
s | The FAX context. |
int fax_rx | ( | fax_state_t * | s, | |
int16_t * | amp, | |||
int | len | |||
) |
Apply T.30 receive processing to a block of audio samples.
Apply T.30 receive processing to a block of audio samples.
s | The FAX context. | |
amp | The audio sample buffer. | |
len | The number of samples in the buffer. |
