The spattern type is used to search through the buffer for another one. Before search start-up, call the spattern.init method in order to initialize the search pattern.
 

uint spattern.search(
uint	src,
uint	size
)

src	Pointer to the beginning of data in order to start a search.
size	Data size.

The offset of the found fragment. If the offset is equal to size, no fragment is found.

src	Buffer where the specified data (search pattern) will be searched.
offset	Offset where the search must be started or proceeded.

The offset of the found fragment. If the offset is equal to the buffer size, no fragment is found.

spattern sp
buf pattern src
...
sp.init( pattern, 0 )
if sp.search( src, 0 ) < *src 
{
   print("The pattern has been found in src buffer!\n")
}
