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);
