Description:
[ CCode ( instance_pos = 5.9 ) ]
[ Version ( since = "1.20" ) ]
public delegate bool CustomMetaTransformFunction (Buffer transbuf, CustomMeta meta, Buffer buffer, Quark type, void* data)
[ Version ( since = "1.20" ) ]
public delegate bool CustomMetaTransformFunction (Buffer transbuf, CustomMeta meta, Buffer buffer, Quark type, void* data)
Function called for each meta in buffer as a result of performing a transformation that yields transbuf.
Additional type specific transform data is passed to the function as data.
Implementations should check the type of the transform and parse additional type specific fields in data that should
be used to update the metadata on transbuf.
Parameters:
| transbuf |
a Buffer |
| meta | |
| buffer |
a Buffer |
| type |
the transform type |
| data |
transform specific data. |
| user_data |
user data passed when registering the meta |
Returns:
