Input Parameters
Name
Type
Description
task
DFTaskPtr
Descriptor of the task.
ptr_attr
const MKL_INT
The parameter to query.
The query routine supports pointer attributes described in the table
"Pointers Supported by the
df?EditPtr
 Task Editor"
. For details, see the
Pointer Attribute
 column in the table.

Status of the routine:
Description
The
df?QueryPtr
 routine returns the pointer of type
ptr_attr
 stored in a Data Fitting task descriptor as parameter
ptr
. Attributes of the pointers supported by the query function are identical to those supported by the editor
df?EditPtr
 editor in the table
"Pointers Supported by the
df?EditPtr
 Task Editor"
.
You can use
df?QueryPtr
 to read different types of pointers including pointers to the vector-valued function and spline coefficients stored in contiguous memory.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
