Returns record at position
pos or empty string if no record exists at given
position.
The yaz_record() function
inspects a record in the current result set at the position
specified. If no database record exists at the given position
an empty string is returned. The
type specifies the form of the returned record.
If type is "string" the record
is returned in a string representation suitable for printing
(for XML and SUTRS). If
type is "array" the record
is returned as an array representation (for structured
records). If type is "raw" the record is returned in its
original raw form.
Records in a result set are numbered 1, 2, ... $hits
where $hits is the count returned by
yaz_hits().
