22 | ******** xxusb_longstack_execute ************************ |
||
23 | |||
24 | Executes stack array passed to the function and returns the data read from the VME bus |
||
25 | |||
26 | Paramters: |
||
27 | hdev: USB device handle returned from an open function |
||
28 | DataBuffer: pointer to the dual use buffer |
||
29 | when calling , DataBuffer contains (unsigned short) stack data, with first word serving |
||
30 | as a placeholder |
||
31 | upon successful return, DataBuffer contains (unsigned short) VME data |
||
32 | lDataLen: The number of bytes to be fetched from VME bus - not less than the actual number |
||
33 | expected, or the function will return -5 code. For stack consisting only of write operations, |
||
34 | lDataLen may be set to 1. |
||
35 | timeout: The time in ms that should be spent tryimg to write data. |
||
36 | |||
37 | Returns: |
||
38 | When Successful, the number of bytes read from xxusb. |
||
39 | Upon failure, a negative number |
||
40 | |||
41 | Note: |
||
42 | The function must pass a pointer to an array of unsigned integer stack data, in which the first word |
||
43 | is left empty to serve as a placeholder. |
||
44 | The function is intended for executing long stacks, up to 4 MBytes long, both "write" and "read" |
||
45 | oriented, such as using multi-block transfer operations. |
||
46 | Structure upon call: |
||
47 | DataBuffer(0) = 0(don't care place holder) |
||
48 | DataBuffer(1) = (unsigned short)StackLength bits 0-15 |
||
49 | DataBuffer(2) = (unsigned short)StackLength bits 16-20 |
||
50 | DataBuffer(3 - StackLength +2) (unsigned short) stack data |
||
51 | StackLength represents the number of words following DataBuffer(1) word, thus the total number |
||
52 | of words is StackLength+2 |
||
53 | Structure upon return: |
||
54 | DataBuffer(0 - (ReturnValue/2-1)) - (unsigned short)array of returned data when ReturnValue>0 |
