bb_save_connections
size_t bb_save_connections(bb_endpoint* ep, void* buf, size_t cap);
Writes all cables into this endpoint's inputs as NUL-terminated UTF-8 text.
Returns the bytes needed, including the NUL. If that exceeds cap,
nothing is written. [non-RT]
size_t n = bb_save_connections(ep, NULL, 0);
char* text = malloc(n);
bb_save_connections(ep, text, n);
/* store `text` next to your parameters */
Format (tab-separated, locale-independent):

Cutoff 0123456789abcdef A -0.300000
bb_load_connections
bb_error bb_load_connections(bb_endpoint* ep, const void* buf, size_t len);
Replaces all cables into this endpoint's inputs with the saved ones. Add your
inputs first. Lines for unknown inputs are skipped. Loading does not change
bb_endpoint_patch_version. [non-RT] Errors: BB_ERR_PARSE.
