* new fields may need to be created, in order to ensure proper function.
|
|
*
|
|
* The arguments are specified in groups of 3: column name, column type,
|
|
* and column size. The column types are specified as integer constants,
|
|
* defined by the enum require_type. Note that the size is specified as
|
|
* the number of equivalent character fields that a field may take up, even
|
|
* if a field is otherwise specified as an integer type. This is due to
|
|
* the fact that some fields have historically been specified as character
|
|
* types, even if they contained integer values.
|
|
*
|
|
* A family should always specify its fields to the minimum necessary
|
|
* requirements to fulfill all possible values (within reason; for example,
|
|
* a timeout value may reasonably be specified as an INTEGER2, with size 5.
|
|
* Even though values above 32767 seconds are possible, they are unlikely
|
|
* to be useful, and we should not complain about that size).
|
|
*
|
|
* \retval 0 Required fields met specified standards
|
|
* \retval -1 One or more fields was missing or insufficient
|
|
*

* \note You should use the constant SENTINEL to terminate arguments, in
|
|
* order to preserve cross-platform compatibility.

* TODO The return value of this function is routinely ignored. Ignoring
|
|
* the return value means that it's mostly pointless to be calling this.
|
|
* You'll see some warning messages potentially, but that's it.
|
|
*
|
|
* XXX This function is super useful for detecting configuration problems
|
|
* early, but unfortunately, the latest in configuration management, sorcery,
|
|
* doesn't work well with this. Users of sorcery are familiar with the fields
|
|
* they will need to write but don't know if realtime is being used. Sorcery
|
|
* knows what storage mechanism is being used but has no high-level knowledge
|
|
* of what sort of data is going to be written.
