# tibrvMsgField

Type

## Declaration

    typedef struct
    {
        char*               name;
        tibrv_u32           size;
        tibrv_u32           count;
        tibrvLocalData      data;
        tibrv_u16           id;
        tibrv_u8            type;
    } tibrvMsgField;

## Purpose

Fields hold data within messages. Programs manipulate the content of field structs using the public struct accessors of this type.

Accessor | Description
`name` | The field’s name. `NULL` signifies the empty string as the field name. Field name strings use the ISO 8859-1 character encoding.
`size` | The size of the field’s `data` (in bytes). For array types, `size` reflects the size (in bytes) of one array element. For TIBRVMSG_STRING, `size` reflects the number of bytes in the string (including the `NULL` terminator, if present). For TIBRVMSG_OPAQUE and TIBRVMSG_XML, `size` reflects the number of bytes of data.
`count` | The number of values in an array field. For array types, `count` is the number of array elements. For example, when a field contains a array of ten 32-bit integers, its `size` is `4`, and its `count` is `10`. (For scalar types, strings, opaque byte sequences and XML data, `count` is `1`. That is, the field contains one string—not an array of characters; one opaque value—not an array of bytes.)
`data` | The field’s data value.
`id` | The field’s identifier. Identifiers are optional, but must be unique within each message.
`type` | A Rendezvous datatype token denoting the type of the field’s `data`.
