Description

Details

struct CamelOperation

struct CamelOperation;

camel_operation_new ()

GCancellable *      camel_operation_new                 (void);

Create a new camel operation handle. Camel operation handles can be used in a multithreaded application (or a single operation handle can be used in a non threaded appliation) to cancel running operations and to obtain notification messages of the internal status of messages.

Returns :

A new operation handle.

camel_operation_cancel_all ()

void                camel_operation_cancel_all          (void);

Cancel all outstanding operations.


camel_operation_push_message ()

void                camel_operation_push_message        (GCancellable *cancellable,
                                                         const gchar *format,
                                                         ...);

Call this function to describe an operation being performed. Call camel_operation_progress() to report progress on the operation. Call camel_operation_pop_message() when the operation is complete.

This function only works if cancellable is a CamelOperation cast as a GCancellable. If cancellable is a plain GCancellable or NULL, the function does nothing and returns silently.

cancellable :

a GCancellable or NULL

format :

a standard printf() format string

... :

the parameters to insert into the format string

camel_operation_pop_message ()

void                camel_operation_pop_message         (GCancellable *cancellable);

Pops the most recently pushed message.

This function only works if cancellable is a CamelOperation cast as a GCancellable. If cancellable is a plain GCancellable or NULL, the function does nothing and returns silently.

cancellable :

a GCancellable

camel_operation_progress ()

void                camel_operation_progress            (GCancellable *cancellable,
                                                         gint percent);

Report progress on the current operation. percent reports the current percentage of completion, which should be in the range of 0 to 100.

This function only works if cancellable is a CamelOperation cast as a GCancellable. If cancellable is a plain GCancellable or NULL, the function does nothing and returns silently.

cancellable :

a GCancellable or NULL

percent :

percent complete, 0 to 100.
