writing contents of array to file

06-26-2002, 06:16 AM

fprintf(string, "%f", array[0]);

That statement above writes to a data file but stops after about a hundreds line are written. The data that is stored in array[0] is created as the file is being written (dynamically??)

How do I code so that I can continously write to a file as the data is being created?

Thanks,

Donald

sprintf(string, " %g", draw_geom_buf.value[0]);
fprintf(output,"%s\n",string);

this the actual code sorry.

Can you explain how this is being achieved?

In a single thread, you're either modifying the array or writing to the file.

Where is the input coming from? You need to control the input loop somehow. Bit difficult to advise without seeing more code really.

I have it. I forgot to fclose(output); this flushes all the data created during the execution of the main program to the output file after the main program is exited.

The data is basically written to the file during the execution of the program then when you exit the program the rest of the data stored in the array is flushed out to the data file.

Without fclose() the rest of the data that is stored in the array is not written to the data file, resulting in a inacurate data file.

Once again fclose() saves the day.
