int oyOptions_Add | ( | oyOptions_s * | options,
|  | oyOption_s * | option,
|  | int | pos,
|  | oyObject_s | object
| ) |  |

add a element to a Options list

Function oyOptions_Add

We must not add any already listed option. (oyFILTER_REG_TOP)

Adding a new element without any checks is as simple as following code:

    *     tmp = oyOption_Copy( option, object );
    *     oyOptions_MoveIn( options, &tmp, -1 );

int oyOptions_DoFilter | ( | oyOptions_s * | opts,

|  | const char * | filter_type
| ) |  |

filter the options

Function oyOptions_DoFilter

The returned options are read in from the Elektra settings and if thats not available from the inbuild defaults. The later can explicitely selected with oyOPTIONSOURCE_FILTER passed as flags argument. advanced options can be filtered out by adding oyOPTIONATTRIBUTE_ADVANCED.

Modules should handle the advanced options as well but shall normally not act upon them. The convention to set them zero, keeps them inactive.

On the front end side the CMM cache has to include them, as they will influence the hash sum generation. The question arrises, whether to include these options marked as non visible along the path or require the CMM cache code to check each time for them on cache lookup. The oyOption_s::flags is already in place. So we use it and do inclusion. Front end options can be filtered as they do not affect the CMM cache.

Parameters

  | opts | the options
  [in] | flags | for inbuild defaults | oyOPTIONSOURCE_FILTER; for options marked as advanced | oyOPTIONATTRIBUTE_ADVANCED; for front end options | oyOPTIONATTRIBUTE_FRONT
  | filter_type | the type level from a registration

The name of that object will come from driver_context_type.

Parameters

  [in,out] | options | options for the device
  [in] | driver_context | driver context
  [in] | driver_context_type | "xml" or something related to the driver
  [in] | driver_context_size | size of driver_context
