| mptCursor | A pointer to an LRD_CURSOR structure. |
| mpszPlaceholder | A pointer to a string containing the placeholder name. |
| mptVarDesc | A pointer to the descriptor of a variable being bound. |
| muliOption | One of the LRD Binding Options. |
| miDBErrorSeverity | The Error Severity Levels of a failure in a database routine. |

Example
In the following example, lrd_assign assigns values to the host variable F_D1 and L_D2. The lr_bind_placeholder function binds the host variable to the placeholders F and L.
/* Insert employee data into the employee table. */
// For Oracle lrd_stmt(Csr2, "insert into employees (emp_firstname,emp_lastname)", "values(:F,:L)", -1, 1 /*Deferred*/, 1 /*Dflt Ora Ver*/, 0); /* For OCBC values in lrd_stmt are represented with "?": "values(?,?)" */ lrd_assign(&F_D1, "Jim", "", 0, 0); lrd_assign(&F_D1, "Bob", "", 1, 0); lrd_assign(&F_D1, "Mike", "", 2, 0); // For Oracle lrd_bind_placeholder(Csr2, "F", &F_D1, 0, 0);
/* For ODBC, use column number as place holder instead of "F": lrd_bind_placeholder(Csr2, "1", &F_D1, 0, 0); */
lrd_assign(&L_D2, "Smith", "", 0, 0); lrd_assign(&L_D2, "Jones", "", 1, 0); lrd_assign(&L_D2, "Anderson", "", 2, 0); // For Oracle
lrd_bind_placeholder(Csr2, "L", &L_D2, 0, 0);
/* For ODBC, use column number as place holder instead of "L": lrd_bind_placeholder(Csr2, "2", &L_D2, 0, 0); */
