| unsigned LRA_initCrl | ( | void * | lists, | |
| unsigned int | len, | |||
| LEM_micr * | crl | |||
| ) |
Initialize a multi-item command/response list.
This routine optimally assigns portions of a supplied region to the various components of a LEM-style multi-item command/response list, and initializes the supplied list anchor block.
Because of RAD750 hardware restrictions, the assigned command list, rounded down to a cache line boundary (32-byte aligned) then extended by six cache lines (192 bytes), must not be accessed by the CPU while the operation is in progress. The result list, on the other hand, cannot have simultaneous CPU acces of the first six cache lines beyond the beginning of the list proper. These restrictions mean that the effective length of these lists is increased when determining whether they fit within the supplied region, but impose no extra restrictions on the relative arrangement of the three lists within the region.
| lists | The address of the region to be used. | |
| len | The length of the region to be used. | |
| crl | The address of the list's anchor block to be filled. |
| LRA_SUCCESS | Success | |
| LRA_CRLSMALL | Region too small for a MICR |

| unsigned LRA_lookupBlk | ( | const LRA_cmptDesc * | cDesc, | |
| const char * | bName, | |||
| int * | block | |||
| ) |
Lookup register block in list.
The register block name is used to locate and return the matching block number in the list of valid blocks for the given component.
| cDesc | The component descriptor. | |
| bName | The register block name. | |
| block | The address of an integer to receive the register block number. |
| LRA_SUCCESS | Success | |
| LRA_INVBLOCK | Invalid register block name |
| unsigned LRA_maxBufSize | ( | unsigned * | size | ) |
Get the maximum size needed for the register data buffer.
This routine returns the maximum size needed for the buffer used to hold the read register data. It assumes the maximum possible wild carding of the register description.
| size | The address of the returned maximum size, in bytes |
| LRA_SUCCESS | Always success |
