NAME
PX_get_data_bytes — Get value from bytes data field
SYNOPSIS
#include <paradox.h>
int PX_get_data_bytes(pxdoc_t *pxdoc, char *data, int len, char
**value)
DESCRIPTION
Reads a data field consisting of an array of bytes into a chunk of
memory and returns the pointer to it in value. The memory is allocated
by this function and must be freed by the calling application. You
should use this function instead of accessing the data directly.
data points to the start of the data field in the record. It must be
calculated by summing up all field length before the field to operate
on and add it to the base pointer of the record.
Note:
This function is deprecated and obsolete if
PX_retrieve_record(3) is used.
RETURN VALUE
Returns 0 if the value is NULL, -1 in case of an error and 1 otherwise.
