Method
GExiv2Metadataopen_buf
Declaration [src]
gboolean
gexiv2_metadata_open_buf (
GExiv2Metadata* self,
const guint8* data,
glong n_data,
GError** error
)
Description [src]
Populate metadata from a memory buffer.
The buffer must be an image format supported by Exiv2. If called multiple times, current metadata will be replaced by the content of the last file opened.
When called on an already filled meta-data object (i.e. one that has already
been filled by a previous call of gexiv2_metadata_open_path()) and the
opening of the new path fails, the object will not revert to its previous
state but be in a similar state after calling GExiv2.Metadata.new.
Parameters
data-
Type: An array of
guint8A buffer containing the data to be read.
The length of the array is specified in the n_dataargument.The data is owned by the caller of the method. n_data-
Type:
glongThe length of the buffer.
error-
Type:
GError **The return location for a recoverable error.
The argument can be NULL.If the return location is not NULL, then you must initialize it to aNULLGError*.The argument will be left initialized to NULLby the method if there are no errors.In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.
