gboolean poppler_attachment_save (PopplerAttachment *attachment, const char *filename, GError **error);
Saves attachment
to a file indicated by filename
. If error
is set, FALSE
will be returned. Possible errors include those in the G_FILE_ERROR domain
and whatever the save function generates.
attachment : |
A PopplerAttachment. |
filename : |
name of file to save |
error : |
return location for error, or NULL .
|
Returns : | TRUE , if the file successfully saved
|
gboolean poppler_attachment_save_to_callback (PopplerAttachment *attachment, PopplerAttachmentSaveFunc save_func, gpointer user_data, GError **error);
Saves attachment
by feeding the produced data to save_func
. Can be used
when you want to store the attachment to something other than a file, such as
an in-memory buffer or a socket. If error
is set, FALSE
will be
returned. Possible errors include those in the G_FILE_ERROR domain and
whatever the save function generates.
attachment : |
A GdkPixbuf. |
save_func : |
a function that is called to save each block of data that the save routine generates. |
user_data : |
user data to pass to the save function. |
error : |
return location for error, or NULL .
|
Returns : | TRUE , if the save successfully completed
|
gboolean (*PopplerAttachmentSaveFunc) (const gchar *buf, gsize count, gpointer data, GError **error);
Specifies the type of the function passed to
poppler_attachment_save_to_callback()
. It is called once for each block of
bytes that is "written" by poppler_attachment_save_to_callback()
. If
successful it should return TRUE
. If an error occurs it should set
error
and return FALSE
, in which case poppler_attachment_save_to_callback()
will fail with the same error.
buf : |
buffer containing bytes to be written. |
count : |
number of bytes in buf .
|
data : |
A location to return an error. |
error : |
user data passed to poppler_attachment_save_to_callback()
|
Returns : |
TRUE if successful, FALSE (with error set) if failed.
