Did you read the whole page?
http://www.postgresql.org/docs/8.1/interactive/spi-spi-execute.html
Especially the bit where it says:
If the return value of the function is SPI_OK_SELECT then you may use
the global pointer SPITupleTable *SPI_tuptable to access the result
rows.
From there you can get the data. There's also the helper functions like
SPI_getvalue().

Hope this helps,
