*************************************************/

|
|
|
/* This function matches a compiled pattern to a subject string, using the
|
|
alternate matching algorithm that finds all matches at once.
|
|
|
|
Arguments:
|
|
code points to the compiled pattern
|
|
subject subject string
|
|
length length of subject string
|
|
startoffset where to start matching in the subject
|
|
options option bits
|
|
match_data points to a match data structure
|
|
gcontext points to a match context
|
|
workspace pointer to workspace
|
|
wscount size of workspace
|
|
|
|
Returns: > 0 => number of match offset pairs placed in offsets
|
|
= 0 => offsets overflowed; longest matches are present
|
|
-1 => failed to match
|
|
< -1 => some kind of unexpected problem
