# Export

When exporting an EMS message, `tibemsd` translates it to a TIBCO FTL message. Not all field types that are supported by EMS map to TIBCO FTL. When `tibemsd` converts these fields, some information about data size is lost. The EMS fields are converted to TIBCO FTL fields as shown here:

EMS Field Type | TIBCO FTL Field Type
--- | ---
`tibems_wchar` | `tibint64_t`
`tibems_byte` | `tibint64_t`
`tibems_short` | `tibint64_t`
`tibems_short_array` | `tibint64_t array`
`tibems_int` | `tibint64_t`
`tibems_int_array` | `tibint64_t array`
`tibems_float` | `tibdouble_t`
`tibems_float_array` | `tibdouble_t array`
