SPI_cursor_find
SPI_cursor_find
SPI_cursor_find - find an existing cursor by name
Synopsis
Portal SPI_cursor_find(const char * name)
Description
SPI_cursor_find
finds an existing portal by
name. This is primarily useful to resolve a cursor name returned
as text by some other function.
Arguments
-
const char *name -
name of the portal
Return Value
pointer to the portal with the specified name, or
NULL
if none was found
Notes
Beware that this function can return a
Portal
object
that does not have cursor-like properties; for example it might not
return tuples. If you simply pass the
Portal
pointer
to other SPI functions, they can defend themselves against such
cases, but caution is appropriate when directly inspecting
the
Portal
.
