Function Documentation

double explain_strtod_or_die ( const char *  nptr,
char **  endptr 
)

The explain_strtod_or_die function is used to call the strtod(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_strtod(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

Parameters:
nptrThe nptr, exactly as to be passed to the strtod(3) system call.
endptrThe endptr, exactly as to be passed to the strtod(3) system call.
Returns:
This function only returns on success, see strtod(3) for more information. On failure, prints an explanation and exits, it does not return.
Example:
This function is intended to be used in a fashion similar to the following example:
 double result = explain_strtod_or_die(nptr, endptr);
