PX_GET_DATA_BYTE(3)					     Library Functions Manual					       PX_GET_DATA_BYTE(3)

NAME
       PX_get_data_byte -- Get value from byte data field

SYNOPSIS
       #include <paradox.h>

       int PX_get_data_byte(pxdoc_t *pxdoc, char *data, int len, char *value)

DESCRIPTION
       Converts  a data field consisting of a single byte into a byte for the host architecture. 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.
