NAME

       DtSearchMessages -- Access and manipulate messages on the DtSearch MessageList

SYNOPSIS

       #include <Dt/Search.h>
       int DtSearchHasMessages(
       ,
       void DtSearchAddMessage(
       const char *msg,
       char *DtSearchGetMessages(
       ,
       void DtSearchFreeMessages(
       );

DESCRIPTION

       The  DtSearch  online search engine may assemble detailed user messages to explain various errors and failures. These messages are designed
       to provide a user with enough information to correct the error.	Often more than one message is	assembled  onto  the  MessageList  as  the
       result  of  a  single  API  call.  The calling code may also append messages to the MessageList prior to display to the user.  All messages
       remain on the MessageList and new messages are appended to the preexisting list until the list is specifically freed by the calling code.

       DtSearchHasMessages returns zero if the MessageList is empty, and returns nonzero if there are any information or error messages  currently
       on the MessageList.

       DtSearchAddMessage appends a message to the end of the MessageList. A message is defined as a zero-terminated C string.

       DtSearchGetMessages  returns a static text buffer containing all current messages on the MessageList. The messages are returned as a single
       flat, zero-terminated C string, with two ASCII linefeed characters between messages (giving the appearance of a	blank  line  between  mes-
       sages).	It  is expected that the calling code will display the text in a message dialog box or its equivalent. The returned buffer address
       is valid until the next call. If the MessageList is currently empty, this function returns a pointer to an empty string.

       DtSearchFreeMessages clears all messages on the MessageList. It is usually called after the user has dismissed a dialog box displaying  the
       current messages.
