This is a small program as a tester for a basic sweep generator for bandwidth testing of AudioScope.sh.
This DEMO is only capable of 4KHz down to about 85Hz and back due to the low bit rate, but it is proof of concept for a much wider variant using a much higher bit rate.

explain_printf_or_die
explain_printf_or_die(3) Library Functions Manual explain_printf_or_die(3)NAME
explain_printf_or_die - formatted output conversion and report errors
SYNOPSIS
#include <libexplain/printf.h>
int explain_printf_or_die(const char *format);
int explain_printf_on_error(const char *format);
DESCRIPTION
The explain_printf_or_die function is used to call the printf(3) system call. On failure an explanation will be printed to stderr, obtained
from the explain_printf(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_printf_on_error function is used to call the printf(3) system call. On failure an explanation will be printed to stderr,
obtained from the explain_printf(3) function, but still returns to the caller.
format The format, exactly as to be passed to the printf(3) system call.
RETURN VALUE
The explain_printf_or_die function only returns on success, see printf(3) for more information. On failure, prints an explanation and
exits, it does not return.
The explain_printf_on_error function always returns the value return by the wrapped printf(3) system call.
EXAMPLE
The explain_printf_or_die function is intended to be used in a fashion similar to the following example:
int result = explain_printf_or_die(format);
SEE ALSO printf(3)

explain_printf(3)
explain printf(3) errors
exit(2) terminate the calling process
