                                   yaz_errno

   (PHP 4 >= 4.0.1)
   yaz_errno -- Returns error number

Description

   int yaz_errno ( resource id)

   Returns an errornumber for the target (last request) identified by id.
   The error code is either a Z39.50 diagnostic code (usually a Bib-1
   diagnostic) or a client side error code which is generated by PHP/YAZ
   itself, such as "Connect failed", "Init Rejected", etc.

   yaz_errno() should be called after network activity for each target -
   (after yaz_wait() returns) to determine the success or failure of the
   last operation (e.g. search). To get a text description of the error,
   call yaz_error().
