sdi_idata_alloc -- allocate and initialize a idata structure for a controller instance

Synopsis

   #include <sys/sdi.h>
   
   HBA_IDATA_STRUCT *sdi_idata_alloc(rm_key_t rm_key, const HBA_IDATA_STRUCT *idata);

Description

sdi_idata_alloc allocates a new hba_idata_v5(D4sdi) structure for a controller instance identified by rm_key.

The information passed in the original idata structure is used in initializing the newly allocated idata structure. The rest of the information is retrieved from the autoconfiguration resource manager database using rm_key.

If the HBA driver has initialized an array of original idata structure members for each controller, it must must pass the correct idata structure member associated with this controller instance.

Arguments

rm_key: Resource manager key for the controller instance.
idata: pointer to original hba_idata_v5(D4sdi) template instance.

Return values

Pointer to a newly allocated idata structure.
