You'll never find the "right answer", since other people probably don't have the same problem as you word-for-word, letter-for-letter, keystroke-for-keystroke.
Try breaking it down into steps instead. You'll get more done, and in doing so, probably figure out where to go next.
1) read it line by line. fgets() does that.
2) Check for BC109 at the beginning of the line. strncmp can do that.
2) break it into tokens. Lots and lots of ways to do that.
3) Put it into the structure. One sscanf would do it in a quick-and-dirty fashion. A safer way would be splitting into tokens and copying or scanning individually.

Can someone tell me how to do this?
Just a thought that entered my mind when learning about structs.
First thought was:
struct one
{
struct two;
}
struct two
{
three;
}
one->two->three
would this be how you would access "three"? (1 Reply)
Dear all,
I'm trying to manipulate a data file and putting a certain lines into one paragraph.

SDL_ConvertAudio(3) SDL API Reference SDL_ConvertAudio(3)NAME
SDL_ConvertAudio - Convert audio data to a desired audio format.
SYNOPSIS
#include "SDL.h"
int SDL_ConvertAudio(SDL_AudioCVT *cvt);
DESCRIPTION
SDL_ConvertAudio takes one parameter, cvt, which was previously initilized. Initilizing a SDL_AudioCVT is a two step process. First of all,
the structure must be passed to SDL_BuildAudioCVT along with source and destination format parameters. Secondly, the cvt->buf and cvt->len
fields must be setup. cvt->buf should point to the audio data and cvt->len should be set to the length of the audio data in bytes. Remem-
ber, the length of the buffer pointed to by buf show be len*len_mult bytes in length.
Once the SDL_AudioCVTstructure is initilized then we can pass it to SDL_ConvertAudio, which will convert the audio data pointer to by
cvt->buf. If SDL_ConvertAudio returned 0 then the conversion was completed successfully, otherwise -1 is returned.
If the conversion completed successfully then the converted audio data can be read from cvt->buf. The amount of valid, converted, audio
data in the buffer is equal to cvt->len*cvt->len_ratio.
EXAMPLES
/* Converting some WAV data to hardware format */
void my_audio_callback(void *userdata, Uint8 *stream, int len);
SDL_AudioSpec *desired, *obtained;
SDL_AudioSpec wav_spec;
SDL_AudioCVT wav_cvt;
Uint32 wav_len;
Uint8 *wav_buf;
int ret;
/* Allocated audio specs */
desired=(SDL_AudioSpec *)malloc(sizeof(SDL_AudioSpec));
obtained=(SDL_AudioSpec *)malloc(sizeof(SDL_AudioSpec));
/* Set desired format */
desired->freq=22050;
desired->format=AUDIO_S16LSB;
desired->samples=8192;
desired->callback=my_audio_callback;
desired->userdata=NULL;
/* Open the audio device */
if ( SDL_OpenAudio(desired, obtained) < 0 ){
fprintf(stderr, "Couldn't open audio: %s
", SDL_GetError());
exit(-1);
}
free(desired);
/* Load the test.wav */
if( SDL_LoadWAV("test.wav", &wav_spec, &wav_buf, &wav_len) == NULL ){
fprintf(stderr, "Could not open test.wav: %s
", SDL_GetError());
SDL_CloseAudio();
free(obtained);
exit(-1);
}
/* Build AudioCVT */
ret = SDL_BuildAudioCVT(&wav_cvt,
wav_spec.format, wav_spec.channels, wav_spec.freq,
obtained->format, obtained->channels, obtained->freq);
/* Check that the convert was built */
if(ret==-1){
fprintf(stderr, "Couldn't build converter!
");
SDL_CloseAudio();
free(obtained);
SDL_FreeWAV(wav_buf);
}
/* Setup for conversion */
wav_cvt.buf=(Uint8 *)malloc(wav_len*wav_cvt.len_mult);
wav_cvt.len=wav_len;
memcpy(wav_cvt.buf, wav_buf, wav_len);
/* We can delete to original WAV data now */
SDL_FreeWAV(wav_buf);
/* And now we're ready to convert */
SDL_ConvertAudio(&wav_cvt);
/* do whatever */
