PX_get_data_alpha — Get alpha data field
Contents
Description
Converts a data field as it is stored in the database file into a string for the given encoding. You must
set the target encoding before in order to recode the string. If you do not set the encoding the data
will be returned as is. 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.
The function allocates memory for the string returned in *value. This memory has to be freed by the
application.
Note:
This function is deprecated and obsolete if PX_retrieve_record(3) is used.
