Overview
The Libreciva mute function controls the radio's mute state.
In order to use the library function, you must include the header file:
<syntaxhighlight>
- include "mute.h"
</syntaxhighlight>
void mute_set(enum smute_e_state state)
This function changes the radio's mute state. The passed parameter is either:
- SMUTE_ON
- SMUTE_OFF
It is recommended that this function is called when the radio application first starts.
enum smute_e_state mute_get()
This function gets the current mute state. Note that this function will only produce an accurate response if mute_set() has been previously called.
Example
<syntaxhighlight>
- include "mute.h"
- include <string.h>
- include <stdio.h>
main(int argc, char *argv[]) {
if (argc==2 && strcmp(argv[1],"on")==0) mute_set(SMUTE_ON) ;
else if (argc==2 && strcmp(argv[1],"off")==0) mute_set(SMUTE_OFF) ;
else { printf("mutectl on|off
") ; return ; }
printf("Mute state is %d
", mute_get()) ; } </syntaxhighlight>
