[section:error_type error_type]

[h4 Synopsis]

Type error type represents the different types of errors that can be raised 
by the library when parsing a regular expression.

   namespace boost{ namespace regex_constants{

   typedef implementation-specific-type error_type;

   static const error_type error_collate;
   static const error_type error_ctype;
   static const error_type error_escape;
   static const error_type error_backref;
   static const error_type error_brack;
   static const error_type error_paren;
   static const error_type error_brace;
   static const error_type error_badbrace;
   static const error_type error_range;
   static const error_type error_space;
   static const error_type error_badrepeat;
   static const error_type error_complexity;
   static const error_type error_stack;
   static const error_type error_bad_pattern;

   } // namespace regex_constants
   } // namespace boost

 
[h4 Description]

The type `error_type` is an implementation-specific enumeration type that may 
take one of the following values:

[table
[[Constant][Meaning]]
[[error_collate][An invalid collating element was specified in a \[\[.name.\]\] block.]]
[[error_ctype][An invalid character class name was specified in a \[\[:name:\]\] block.]]
[[error_escape][An invalid or trailing escape was encountered.]]
[[error_backref][A back-reference to a non-existant marked sub-expression was encountered.]]
[[error_brack][An invalid character set \[...\] was encountered.]]
[[error_paren][Mismatched '(' and ')'.]]
[[error_brace][Mismatched '{' and '}'.]]
[[error_badbrace][Invalid contents of a {...} block.]]
[[error_range][A character range was invalid, for example \[d-a\].]]
[[error_space][Out of memory.]]
[[error_badrepeat][An attempt to repeat something that can not be repeated - for example a*+]]
[[error_complexity][The expression became too complex to handle.]]
[[error_stack][Out of program stack space.]]
[[error_bad_pattern][Other unspecified errors.]]
