NAME

       PQgeterror, PQseterror, PQgetErrorField - libpqtypes error system management functions

SYNOPSIS

       #include <libpqtypes.h>

       char *PQgeterror(void);
       void PQseterror(const char *format, ...);
       char *PQgetErrorField(int fieldcode);

DESCRIPTION

       The  libpqtypes library maintains a per-thread global error message.  The error message is
       managed by PQgeterror() and PQseterror().

       PQseterror() takes a regular printf compatible format string for  setting  the  libpqtypes
       error message.

       PQgetErrorField()  gets  an  error field from the last executed query.  The error field is
       only set by PQparamExec and PQparamExecPrepared.  When using libpq functions  that  return
       results, like PQexec, continue to use PQresultErrorField.

       To  clear  the  libpqtypes  error  message,  call  PQseterror() with a NULL format string:
       PQseterror(NULL);  This will also clear error fields.

RETURN VALUE

       PQgeterror() returns the last error message for the calling thread.  It will never  return
       NULL.

       PQgetErrorField()  returns the error field, referenced by fieldcode, for the last executed
       query.  NULL is returned if no value exists.

EXAMPLES

       None.
