NAME

       PX_retrieve_record — Returns record in Paradox file

SYNOPSIS

       #include <paradox.h>

       pxval_t ** PX_retrieve_record(pxdoc_t *pxdoc, int recno)

DESCRIPTION

       Returns  the  record with the given number in a Paradox file. The first record has number 0, the last one
       has number_of_records-1.

       If you are accessing several records, do it in ascending order, because this is the most efficient way.

       The return value is an array of field values. Each value is stored in a structure like the following:

       typedef struct px_val pxval_t;
       struct px_val {
       char isnull;
       int type;
       union {
       long lval;
       double dval;
       struct {
       char *val;
       int len;
       } str;
       } value;
       };

       The element isnull is set to 1 if the value is NULL otherwise it is set to 0. type                is  the
       type of the paradox field as defined in paradox.h.  A field value can be either a long int, a double or a
       string, depending on the paradox field type. The paradox field types pxfShort, pxfLong, pxfDate, pxfTime,
       pxfLogical, and pxfAutoInc are returned as long int values.  pxfTimestamp, pxfNumber, and pxfCurrency are
       returned as double values and all remaining paradox field types are stored as strings with the length  in
       value.len.  You  can  rely  on  strings  being  Null  terminated.  Blobs are stored as string but are not
       guarented to be Null terminated.

       The paradox field types pxfTimestamp, pxfTime, an pxfDate use an uncommon format which can  be  converted
       into a string with PX_timestamp2string(3), PX_time2string(3), and PX_date2string(3).

RETURN VALUE

       Returns a pointer on success and NULL on failure.
