# Add Opaque Byte Sequence

Convenience Method

## Declaration

    TibrvStatus addOpaque(
        const char*    fieldName,
        const void*    value,
        tibrv_u32      size
        tibrv_u16      fieldId=0);

## Purpose

Add a field containing an opaque byte sequence.

Parameter | Description
`fieldName` | Create the new field with this name.
`value` | Add a new field that contains this opaque buffer. The method copies the data into the new message field.
`size` | When adding an opaque buffer, the program supplies the size (in bytes) of the data in this parameter.
`fieldId` | Create the new field with this identifier. Zero is a special value that signifies no field identifier. All non-zero field identifiers must be unique within each message. It is illegal to add a field that has both a `NULL` field name, and a non-zero field identifier.
