Details
PopplerAttachmentSaveFunc ()
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.
|
buffer containing bytes to be written. [array length=count][element-type guint8] |
|
number of bytes in buf. |
|
user data passed to poppler_attachment_save_to_callback(). [closure]
|
|
GError to set on error, or NULL
|
Returns : |
TRUE if successful, FALSE (with error set) if failed. |
poppler_attachment_save ()
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.
|
A PopplerAttachment. |
|
name of file to save |
|
return location for error, or NULL. [allow-none]
|
Returns : |
TRUE, if the file successfully saved |
poppler_attachment_save_to_callback ()
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.

a function that is called to save each block of data that the save routine generates. [scope call] |
