66 number of buffers attached to the field then

72 storage will be allocated to hold the reformatted buffer.
73 This storage must be release by calling
75 when it is no longer required.
78 field option is not set then no extra storage is allocated.
79 The field buffer may be set by calling

99 programmatically set by calling
100 .Fn set_field_status .
101 The maximum growth of a dynamic field can be set by calling
103 which limits the fields rows if the field is a multiline field or the
104 fields columns if the field only has a single row.
