Re: regcomp returning 13 error

Seriously, from the API doc:
If the regcomp() function is successful, it returns 0. Otherwise, it returns an error code that you can use in a call to the regerror() function, and the content of preg is undefined.

This is for 7.2 but you can change version

Subject: regcomp returning 13 error

Im trying to use regcomp/regexec to extract emails from a long string.
When i test the code, the return code is 13. Where can i find out what that means?

code:

P eminnote B export
*-------------------------------------------------------------------
D eminnote PI 60 dim(20) D claimin 7 0 const D datain 1000 const

d data s 1000a inz varying d regex_ph_nbr ds inz likeds(regex_t) d dsrm ds inz likeds(regmatch_t) dim(100) d ast s 60 inz(*all'*') d pattern s 1000a inz varying d rc s 10i 0 inz(0) d rtnval s 60 dim(20) d rtnval_c s 3 0 d email s 60

clear rtnval;
data = datain;
open CLPHONEL11;

pattern =
'[a-z0-9]+([-+._][a-z0-9]+){0,2}@.*?(\.(a;'
+'(?:[cdefgilmnoqrstuwxz]|ero|(?:rp|si)a)|'
+'b(?:[abdefghijmnorstvwyz]iz)|c(?:'

;

rc = regcomp(regex_ph_nbr :pattern :REG_EXTENDED) ; if rc = 0 ;
dow '1' ;
rc = regexec(regex_ph_nbr:
data:
regex_ph_nbr.re_nsub :
dsrm :

if rc <> 0 ;
leave ;
endif ;

email =
%subst(data:dsrm(1).rm_so+1:dsrm(1).rm_eo-dsrm(1).rm_so);

setll (email:claimin) clphonel11;
if not %equal;
rtnval_c += 1;
rtnval(rtnval_c) = email;
endif;

%subst(data:dsrm(1).rm_so+1:dsrm(1).rm_eo-dsrm(1).rm_so) = ast;
enddo ;
endif ;
regfree(regex_ph_nbr) ;

close CLPHONEL11;
return rtnval;
