Name
algInit()
– initialize an algorithm instance
║
Synopsis
XDAS_Int32 algInit(IALG_Handle handle, IALG_MemRec
memTab[], IALG_Handle parent, IALG_Params *params);
║ Arguments
IALG_Handle handle; /* algorithm instance handle*/
IALG_memRec memTab[]; /* array of allocated buffers */
IALG_Handle parent; /* handle to the parent instance */
IALG_Params *params; /* algorithm initialization
parameters */
║ Return Value
IALG_EOK; /* status indicating success */
IALG_EFAIL; /* status indicating failure */
║ Description
algInit()
performs all initialization necessary to complete the run-time
creation of an algorithm instance object. After a successful return
from
algInit(), the instance object is ready to be used to process data.
The first argument to
algInit()
is a handle to an algorithm instance. This
value is initialized to the base field of
memTab[0].
The second argument is a table of memory records that describe the base
address, size, alignment, type, and memory space of all buffers allocated
for an algorithm instance. The number of initialized records is identical to
the number returned by a prior call to
algAlloc().
The third argument is a handle to the parent instance object. If there is no
parent object, this parameter must be set to
NULL.
The last argument is a pointer to a structure that defines the algorithm
initialization parameters.
For more details, see TMS320 DSP Algorithm Standard API Reference
(literature number SPRU360).

Note:
If the fourth argument is set to
NULL
, default parameters are used.
