You missed calling glp_create_index. See working example below.

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);
}
