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.
