Re: [vdr] plugin writing - need help with C

Hi.

I'm modifying a non-published pvrinput variation which sends IR commands to a set box box - specifically, the channel number stored in channels.conf.

12345J2:6:C12:C:0:301:300:305:A1:62006:0:1009:0 FOODJ2:63:C12:C:0:301:300:305:A1:62008:0:1019:0 ^^ - channel number to send to external digi-box

It works fine, sending single-digit channel numbers but fails to send double digit. i.e. channels 1-9 are ok, but 10+ fail.

This fails because there are only codes in the lircd.conf for 0-9.

Here's an excerpt from the plugin which sends the commands:

redremote.h

<snip> class cRedRemote : public cThread { public: cRedRemote(); ~cRedRemote();

    int  Open();
    void Tune(int channel);
    void Send(char *text);

<snip>

redremote.c

<snip> void cRedRemote::Send(char *text) {

char buf[100];
snprintf(buf,sizeof(buf), "SEND_ONCE ADB_ICAN3000 %s\n",text);

write(fd,buf,strlen(buf));

close(fd); fd = -1; }

<snip>

My question is this. I need to modify the channel sent, so that double (or triple) channel numbers are sent as '6 3' or '1 1 7' rather than '63' or '117'. i.e. put spaces between the letters.

I'm really out of my depth - can anyone point me in the right direction?

Thanks

Simon

You can try something like that:

char txt2[strlen(txt) * 2]; int i = 0; int j = 0; while (i < strlen(txt) - 1) { txt2[j] = txt[i]; i++; j++; txt2[j] = ' '; j++; } txt2[j] = txt[i]; j++; txt2[j] = '\0';
