NAME

RegularExp::Match2 - instance method

TEMPLATE

matchedLength = int Match2(char * string1, char * string2, int size1 = -1, int size2 = -1, int pos = 0, int stopMatchAt = cMaxInt, RegExRegs * regs = NULL)

SPECIFIERS

public

DESCRIPTION

Match2 checks whether the substring starting at pos in the string, which is obtained from the concatenation of string1 and string2, matches the regular expression.
This method as well as the method SearchForward2 and the method SearchBackward2 are only used by the class GapText because the GapText stores its contents internally in two separate strings.

ARGUMENTS

char * string1: first string to be matched
char * string2: second string to be matched
int size1 = -1: the length of the string1 argument. If it is -1, then the length is determined by the terminating zero character.
int size2 = -1: the length of the string2 argument. If it is -1, then the length is determined by the terminating zero character.
int pos = 0: index where to start searching
int stopMatchAt = cMaxInt: how many characters to try
RegExRegs * regs = NULL: after return contains information about (...) subexpressions

RETURN ARGUMENT

int matchedLength: the length of the matched substring or -1 if no match
