* "sscanf" scans the given string for items specified, and assigns

* Calling sequence:
|

* ret = sscanf(str,fmt,p1,p2,...)
|
||
* Where:
|
||
* ret = the number of items successfully matched & assigned
|
||
* EOF returned if encountered on input
|
||
* str -> a (null terminated) string to scan
|
||
* fmt -> a string specifying how to parse the input
|
||
* p1,p2,... -> where matched items get stored
