- by the library when parsing a regular expression.

- [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.]]
