You missed calling glp_create_index. See working example below.

Best regards

Example:

int main (int argc, char *argv[])
{
    const char n[] = "z_0_0";
    glp_prob* lp;
    int c;

    lp = glp_create_prob();
    glp_add_cols(lp, 1);
    glp_set_col_name(lp, 1, n);
    glp_create_index(lp);

    c = glp_find_col(lp, n);
    printf("Column number: %d\n", c);
    glp_delete_prob(lp);
}
