problem with *char to string conversion

[dumas9]

This is my code:

// returns the value of this preference at index 0
	ifail = PREF_ask_char_value("ProcessAdmin", 0, &adminGrpRle);
	CHECK_IFAIL(ifail);
	
	string adminStrng = string(adminGrpRle);
	posn = adminStrng.find(COLON_SEPARATOR);
		if (posn != string::npos)
		{
			grp = adminStrng.substr(0,posn);
			rle = adminStrng.substr(posn+1, string::npos);
			groupRoleMap.insert(pair<string, string>(grp, rle));
		}

PREF_ask_char_value is a function API that returns a *char - adminGrpRle. In this case it's value is: 0x7ff45060"Process:process_admin"
Value of posn returned is 7 - which is also correct.
I need to split this returnd character string into two strings - Process and process_admin. However the two string variables grp and rle only show <Bad Ptr>.

Any suggestions as to what I am doing wrong ????

Thanks....
