* "fread" reads NI items of size SZ from stream SP and deposits them
|
||
* at BUFF.
|
||
*
|
||
* Calling sequence:
|
||
* rval = fread(buff,size,nitems,stream)
|
||
* Where:
|
||
* buff -> where to read to
|
||
* size = number bytes in each item
|
||
* nitems = number bytes read/to read
|
||
* stream -> file
|
||
*
|
||
* rval = number items successfully read
|
||
*
|
||
* Edits:
|
||
* 8-Feb-84 whf return nitems actually read for EOF.
