NAME

       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.
