GetPhysical

GetPhysical Translate logical addresses to physical ones

OSErr GetPhysical( addresses, physicalEntryCount);

LogicalToPhysicalTable * addresses is a translation table

entries

returns Error Code; 0=no error

The GetPhysical function translates logical addresses into their

corresponding physical addresses.

addresses is a translation table, that is, an array of ordered pairs

(address and count).

physicalEntryCount specifies the number of physical entries to translate.

Returns: an operating system Error Code.

noErr (0) No error

paramErr (-50) Error in parameter list

notLockedErr (-623) Specified range of memory is not locked

interruptsMaskedErr (-624) Called with interrupts masked

Notes: GetPhysical translates up to the size of the table or until the translation

is completed, whichever comes first. If GetPhysical is called with a table

size of 0, the number of table entries needed to translate the entire address

range is returned. On exit from this function, the virtual information is

updated to indicate the next virtual address and the number of bytes left to

translate. The logical address range must be locked to ensure validity of the

translation data.
