Hi All,

 

I am using embedded Postgres ‘C’ file to make function calls to the sql. I have a .pgc (a ‘C’ file with sql statements) and .sql file.

 

I have a pointer array that looks like this:

typedef struct {

                char* displayName;

} DisplayName;

 

DisplayName* displayName_list = calloc(5, sizeof(*displayName_list));

 

displayName_list = response->displayName_list

 

Assume that response->displayName_list holds the list of names to be sent to the sql function. Below is the similar sql func:

 

CREATE OR REPLACE FUNCTION prepare_names,TEXT[])

        RETURNS VOID AS '

………………………………….

 

I need to convert that pointer which holds the list of names to the sql func as an array. Please help me on this part.

 

Thanks and Regards,

Siva.
