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 \digit construct.

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.

Definition at line 48 of file regexp.h.

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.
