Regarding regular expressions in Solaris

Hi,

Am writing one C program for one of my module and facing one problem
with the regular expression functions provided by the library libgen.h
in solaris.

In this library we are having two functions to deal with
the regular expressions

char *regcmp(const char *string1, /* char *string2 */ ,
int /*(char*)0*/); ------this function is to compile the regular
expression.In case of failure it will return NULL.

char *regex(const char *re, const char *subject, /*
char *ret0 */ ...);---------This function is used to execute the
compiled expression against the subject string.
Problem

Compiled and executed the following regular expression
using the above two function like below.

char *name = regcmp("[A-Z]*",(char*)0) ;
const char *newcursor = regex(name,"ps" );

In the above case written the regular expression only to check
whether the given value is capitals or not. To check this one I
submitted the value "ps" in lower case. Still the regular expression
is executing succefully wit out failure.In the above case it shold
have to fail but still it is successful. The regex function is not
returning NULL in this case.

If anybody knows abot this please let me know.
Regards
Sunil.

Dear All In Perl when we are checking some conditions using regular expression we can ignore the case sensitive of a string using the following regular expression /(^)|/|(\.\.)/i.

Hi, I am replaceing a big string using different regular expressions (see some example at the end of the message). The problem is whenever I apply a "replace" it makes a new copy of string and I want to avoid that. My question here is if there is a way to pass either a memory stream or array of "find", "replace" expressions or any other way to avoid multiple copies of a string. Any help will be highly appreciated

I'm kind of disappointed with the re regular expressions module. In particular, the lack of support for recursion ( (?R) or (?n) ) is a major drawback to me. There are so many great things that can be accomplished with regular expressions this way, such as validating a mathematical expression or parsing a language with nested parens, quoting or expressions. Another feature I'm missing is once-only subpatterns and possessive quantifiers...
