Beware
"@???
Is a legal email address. The local-part stops at the last @ sign, not the
first. Suggest recasting your code to use the strrchr() function instead.

I'm currently using this:
typedef struct email_struct {
char localpart[64];
char domain[64];
} _email_struct;
typedef struct lscan_structure {
...
_email_struct lpart_domain;
...
char emailaddy[128];
...
} _lscan;
/** this function returns the localpart and the domain section of an email
in any given string */
_email_struct getlocalp_domain(char * emailaddr, _email_struct lpart_domain)
{
int i = 0;
memset(lscan.emailaddy, 0x0, sizeof(lscan.emailaddy));
sprintf(lscan.emailaddy, "%s", emailaddr);
if (!chk_email(lscan.emailaddy)) { /** simple email validation check */
i = strrchr(lscan.emailaddy, "@");
strncpy(lpart_domain.localpart, lscan.emailaddy, i);
lpart_domain.localpart[i] = '\0';
strcpy(lpart_domain.domain, lscan.emailaddy + i + 1);
} else {
/** tell user, email supplied is a non-valid email address */
}
return(lpart_domain);
} /** getlocalp_domain */
I'm zero'in out 'lscan.emailaddy' because I reuse the function a few times
in a for loop [as recipient count as an attribute] and if I don't zero it
out, I have some left over characters at the end from the last iteration of
the loop. Had a few problems with casting but after a bit of tweaking it
worked nicely.
Thanks for that, I wouldn't have guessed such an obscure email would exist
