There is really important wrong, but I couldnt find

struct guitar active;
char *buffer_char3;
while(!feof(ptdata))
{
fgets(buffer[0],26, ptdata);
fgets(buffer[1],26, ptdata);
fgets(buffer[2],26, ptdata);
fgets(buffer[3],26, ptdata);
fgets(buffer[4],26, ptdata);


active.serial=integer_analys(buffer[0]);
active.price=integer_analys(buffer[1]);

buffer_char = strtok (buffer[2], bracket);
buffer_char = strtok (NULL, bracket);


buffer_char2 = strtok (buffer[3], bracket);
buffer_char2 = strtok (NULL, bracket);


buffer_char3 = strtok (buffer[4], bracket);
buffer_char3 = strtok (NULL, bracket);

how can I convert buffer_char3 to active.model ( model is char
array of guitar struct component)

I have tried to find for 4 days, I did everything but I couldnt
help me please
