Enumeration Type Documentation
Possible errors that can occur during matching. 
- Enumerator: 
- 
| csrxNoError | No problems during matching. |  | csrxNoMatch | The pattern didn't match the string. |  | csrxBadBraces | There was an invalid \{.
..\} construct in the regular expression. A valid \{...\} construct must contain either a single number, or two numbers in increasing order separated by a comma. |  | csrxBadPattern | There was a syntax error in the regular expression. |  | csrxBadRepetition | A repetition operator such as ? or * appeared in a bad position (with no preceding subexpression to act on). |  | csrxErrCollate | The regular expression referred to an invalid collating element (one not defined in the current locale for string collation). |  | csrxErrCharType | The regular expression referred to an invalid character class name. |  | csrxErrEscape | The regular expression ended with \. |  | csrxErrSubReg | There was an invalid number in the \digitconstruct. |  | csrxErrBrackets | There were unbalanced square brackets in the regular expression. |  | csrxErrParentheses | An extended regular expression had unbalanced parentheses, or a basic regular expression had unbalanced \( and\). |  | csrxErrBraces | The regular expression had unbalanced \{and\}. |  | csrxErrRange | One of the endpoints in a range expression was invalid. |  | csrxErrSpace | Out of memory. |  | csrxErrUnknown | Unknown error. |

Flags for regular expression matching. 
- Enumerator: 
- 
| csrxIgnoreCase | Ignore case when matching letters. |  | csrxNewLine | Treat a newline in string as dividing string into multiple lines, so that $can match before the newline and^can match after.
Also, don't permit . to match a newline, and don't permit[^...] to match a newline. 
Otherwise, newline acts like any other ordinary character.  |  | csrxNotBOL | Do not regard the beginning of the specified string as the beginning of a line; more generally, don't make any assumptions about what text might precede it. |  | csrxNotEOL | Do not regard the end of the specified string as the end of a line; more generally, don't make any assumptions about what text might follow it. |
