Subject: Bugfix: provide static variable "fll_error_string_null_s".
X-Git-Tag: 0.5.2~53
X-Git-Url: https://git.kevux.org/?a=commitdiff_plain;h=f28fcb64d3b96ce160361deacd81c0d7581b84f4;p=fll

Bugfix: provide static variable "fll_error_string_null_s".

When using the fl_color_print functions, the context before and after pointers may safely be NULL.
When using the printf functions, the context before and after pointers cannot safely be NULL.

In the second case, a global static is now provided that is essentially a NULL string of a compatible type.
