Declaration

tibrv_status tibrvMsg_Updatescalar_type(
   tibrvMsg       message,
   const char*    fieldName,
   scalar_type     value);
tibrv_status tibrvMsg_Updatescalar_typeEx(
   tibrvMsg       message,
   const char*    fieldName,
   scalar_type     value,
    tibrv_u16     fieldId);

Purpose

Update a field containing a scalar value.

Remarks

Each convenience function in this family locates a field (by name or identifier) and updates its data.

The type of the existing field (within the message) and the type of the updating value must match.
