Converts a string to a gint64 value.
This function behaves like the standard strtoll() function
does in the C locale. It does this without actually
changing the current locale, since that would not be
thread-safe.
This function is typically used when reading configuration
files or other non-user input that should be locale independent.
To handle input from the user you should normally use the
locale-sensitive system strtoll() function.
If the correct value would cause overflow, G_MAXINT64 or G_MININT64
is returned, and ERANGE is stored in errno. If the base is
outside the valid range, zero is returned, and EINVAL is stored
in errno. If the string conversion fails, zero is returned, and
endptr returns nptr (if endptr is non-NULL).
