void
mpd_set_string(mpd_t *result, const char *s, mpd_context_t *ctx)
{
	uint32_t status = 0;

	mpd_addstatus_raise(ctx, status);
}

Example #2

File: test.c Project: gicho/sst

    mpd_context_t ctx;
    mpd_t *n;
    char *sn = NULL;
    uint32_t res = 0;

    mpd_maxcontext(&ctx);

    n = mpd_qnew();

    if (!n) {
        die("Allocating new number failed\n");
    }

    mpd_qset_string(n, NUMBER1, &ctx, &res);

    sn = mpd_to_sci(n, 0);

    if (strcmp(sn, NUMBER1) != 0) {
