PQgeterror(3)		       libpqtypes Manual		 PQgeterror(3)

NAME
       PQgeterror,  PQseterror, PQgetErrorField - libpqtypes error system man‐
       agement 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 set‐
       ting 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.
