set a data server variable
#include <ds.h> int ds_set( ds_t dsdes, char *variable_name, char *variable_data, int data_len );
The ds_set() function passes the data variable_data to the data server identified by dsdes. The data server stores the data in the variable whose name is given by variable_name, overwriting any existing value.
To display the modified data on an HTML page, use the qnxvar token with the read tag. See the description of slinger in the TCP/IP User's Guide.
See the Writing Data Server Applications chapter.
