Input Parameters

Description
srctask
const VSLConvTaskPtr
 for
vslConvCopyTask
const VSLCorrTaskPtr
 for
vslCorrCopyTask
Pointer to the source task descriptor.
Output Parameters
Name
Type
Description
newtask
VSLConvTaskPtr*
 for
vslConvCopyTask
VSLCorrTaskPtr*
 for
vslCorrCopyTask
Pointer to the new task descriptor.
status
int
Current status of the source task.
Description
If a task object
srctask
 already exists, you can use an appropriate
vslConvCopyTask
/
vslCorrCopyTask
 routine to make its copy in
newtask
. After the copy operation, both source and new task objects will become committed (see Introduction to Convolution and Correlation for information about task commitment). If the source task was not previously committed, the commitment operation for this task is implicitly invoked before copying starts. If an error occurs during source task commitment, the task stores the error code in the status field. If an error occurs during copy operation, the routine returns a
NULL
 pointer instead of a reference to a new task object.
