regex_find_sf


Name:
regex_find_sf - Check if a regex is included in a stream
Synopsis:
string istream -> boolean  
Examples:
See examples of regex_find, exchange second string with a file.  
Description:
Takes the first argument. Converts to regex  
and calls regexec to find out if this regex matches the
stream. Reports success/failure in a boolean true/false.
Parameters:
in: first argument  : a string which will be converted  
to a regex by a regcomp call.
second argument : an istream where this
regex should be matched.
out: true/false telling if there is/is no match.
Bugs:
-  
Diagnostics:
Will raise an /InvalidRegexError if regcomp cannot  
compile the regex. Try immidiate
:regerror = to find out why!
Remarks:
Does _not_ return any information about the matched  
expression more than matched/not matched; use lower
level commands regcomp, regexec if in need!
