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