.SH DESCRIPTION
.sp
A \fI\%gearman_task_st\fP represents a \fItask\fP. Work that is sent by a \fIclient\fP to a gearman server is seen as a task (a \fIworker\fP recieves a task in the form of a \fIjob\fP.
.sp
Tasks, i.e. \fI\%gearman_task_st\fP are created by calling either \fBgearman_execute()\fP, \fBgearman_client_add_task()\fP, or \fBgearman_client_add_task_background()\fP.
.sp
\fBgearman_client_add_task_status()\fP can also create \fI\%gearman_task_st\fP, these tasks will be used to
monitor a previously created \fI\%gearman_task_st\fP.
.sp
\fI\%gearman_task_free()\fP is used to free a task. This only needs to be
done if a task was created with a preallocated structure or if you want to clean up the memory of a specific task.
.sp
\fI\%gearman_task_set_context()\fP sets the given context of the \fI\%gearman_task_st\fP. The context can be used to pass information to a \fI\%gearman_task_st\fP.
.sp
\fI\%gearman_task_context()\fP returns the context that was used in the creation of the \fI\%gearman_task_st\fP (or that was set with \fI\%gearman_task_set_context()\fP.
.sp
\fI\%gearman_task_data()\fP returns the current data that has been returned to the task. \fI\%gearman_task_data_size()\fP will give you the size of the value. \fI\%gearman_task_take_data()\fP is the same as \fI\%gearman_task_data()\fP but the value that is returned must be freed by the client (\fIfree(3)\fP). \fI\%gearman_task_recv_data()\fP can be used with pre\-allocated buffers.
.sp
\fI\%gearman_task_is_known()\fP, \fI\%gearman_task_is_running()\fP, \fI\%gearman_task_numerator()\fP, and \fI\%gearman_task_denominator()\fP, return values related to the last status update that was made to the \fI\%gearman_task_st\fP. They do not cause the \fI\%gearman_task_st\fP to update itself.
.sp
\fI\%gearman_task_error()\fP return the last error message that the
\fI\%gearman_task_st\fP encountered. \fI\%gearman_task_return()\fP
return the last \fBgearman_return_t\fP stored. A value of
\fBGEARMAN_UNKNOWN_STATE\fP means that the task has not been submitted to
server yet, or that no function was available if the job has been submitted.
.SH RETURN VALUE
.sp
Various. Values that are returned by \fI\%gearman_task_take_data()\fP must have \fIfree(3)\fP called on them.
