+
+include/zck.h:68:1: error: unknown type name 'ssize_t'; did you mean 'size_t'?
+   68 | ssize_t zck_read(zckCtx *zck, char *dst, size_t dst_size)
+      | ^~~~~~~
+      | size_t
+include/zck.h:81:1: error: unknown type name 'ssize_t'; did you mean 'size_t'?
+   81 | ssize_t zck_write(zckCtx *zck, const char *src, const size_t src_size)
+      | ^~~~~~~
+      | size_t
