NAME
explain_strtof_or_die - convert string to number and report errors
SYNOPSIS
#include <libexplain/strtof.h>
float explain_strtof_or_die(const char *nptr, char **endptr);
float explain_strtof_on_error(const char *nptr, char **endptr))
DESCRIPTION
The explain_strtof_or_die function is used to call the strtof(3) system
call. On failure an explanation will be printed to stderr, obtained
from the explain_strtof(3) function, and then the process terminates by
calling exit(EXIT_FAILURE).
The explain_strtof_on_error function is used to call the strtof(3)
system call. On failure an explanation will be printed to stderr,
obtained from the explain_strtof(3) function, but still returns to the
caller.
nptr The nptr, exactly as to be passed to the strtof(3) system call.
endptr The endptr, exactly as to be passed to the strtof(3) system
call.
RETURN VALUE
The explain_strtof_or_die function only returns on success, see
strtof(3) for more information. On failure, prints an explanation and
exits, it does not return.
The explain_strtof_on_error function always returns the value return by
the wrapped strtof(3) system call.
EXAMPLE
The explain_strtof_or_die function is intended to be used in a fashion
similar to the following example:
float result = explain_strtof_or_die(nptr, endptr);
