# lrc_variant_scode

Assignment to Variants

Assigns a string to an error code value in a variant.

    VARIANT lrc_variant_scode( const char* errcode );

    VARIANT lrc_variant_scode_by_variant( const char* errcode );

errcode | A character string representing an error code value.

The lrc_variant_scode function converts a string containing a system error code value to an error code stored in a variant.

Be careful not to use lrc_variant_scode to create a variant of any type other than an scode error variant. For example, to create a variant to pass a long value to a function that takes a variant argument, use lrc_variant_long.

You create dynamic values for errcode in one of two ways. Either use the standard parameterization methods, or generate a string variable with the value you want to store in an scode variant. The example shows how to do this.

You can also pass a string literal:

VARIANT var = lrc_variant_scode("-2147352572");

The additional function lrc_variant_scode_by_variant is used when a variant to the variant of a system error is required.

The lrc_variant_scode_by_variant function converts a string containing a system error code value to an error code and returns a variant containing a reference to the variant containing the value.

## Return Values

lrc Return Values

## Parameterization

All arguments can be parameterized using standard parameterization.

## Example

This example shows two ways of creating an scode variant with dynamic data.

    VARIANT var ;
    char varVal[80];
    char errVal[15];
    int i;

    /* To use a variable in the call to lrc_variant_scode:
    Get an error code string however appropriate for your test */

    my_get_error_code_function(errval );
    lr_output_message("err val = %s", errval );

    //Action.c(11): err val = -9876543
    // Pass the string variable as the function argument
    var = lrc_variant_scode(errval );
    lrc_print_variant(var);

    // Action.c(15): Variant of type: scode ,with value: -9876543
    /* To use parameterization in the call to lrc_variant_scode:
        Use standard parameter semantics. Either define
        the parameter in the script, or retrieve it from input. */

    for (i = 0; i<4; i++) {
    /* The parameter errcode is defined in the script with values:
    -2147352572
    -200000000
    -300000000
    -400000000 */

    	var = lrc_variant_scode("<errcode>");
    	lrc_print_variant(var);
    	lr_advance_param("errcode");
    }

    Example: Output:
    Action.c(31): Variant of type: scode ,with value: -2147352572
    Action.c(31): Variant of type: scode ,with value: -200000000
    Action.c(31): Variant of type: scode ,with value: -300000000
    Action.c(31): Variant of type: scode ,with value: -400000000
