/* This file should be included from files implementing strbuf. The including file
 * should define the following macros:
 * _STRBUF_DATA_TYPE
 * _STRBUF_CSIZE
 * _STRBUF_STRUCT_NAME
 * _STRBUF_STRLEN_FUNC(x)
 * _STRBUF_STRESCAPE_FUNC(x)
 * _STRBUF_STRSTR_FUNC(x, y)
 * _STRBUF_MAGIC
 * _STRBUF_MAGIC_STR
 * See how it's done in eina_ustrbuf.c and eina_strbuf.c. This just makes things
 * a lot easier since those are essentially the same just with different sizes.
