SPI_cursor_find — find an existing cursor by name
Portal SPI_cursor_find(const char * name
)
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.
const char * name
name of the portal
pointer to the portal with the specified name, or NULL if none was found
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.
