type_find_helper_for_data_with_extension
Description:
[ Version ( since = "1.16" ) ]
public Caps? type_find_helper_for_data_with_extension (Object? obj, uint8[] data, string? extension, out TypeFindProbability prob)
Tries to find what type of data is contained in the given data, the assumption being that the data represents the beginning of the
stream or file.
All available typefinders will be called on the data in order of rank. If a typefinding function returns a probability of
MAXIMUM, typefinding is stopped immediately and the found
caps will be returned right away. Otherwise, all available typefind functions will the tried, and the caps with the highest probability will be
returned, or null if the content of data could not be identified.
When extension is not null, this function will first try the typefind functions for the given extension, which might
speed up the typefinding in many cases.
