From small amount of view and replies I didn't think anyone was particularly interested. The views seem to have gone up a lot though so here it is.
I echoed to a variable but appended nulls and hex encoded to preserve them. Had to also trim the white space from the end but it worked. Could just have easily used printf and inserted nulls using flags but I got this working and it was good enough.

Again, what's the different if set option... (1 Reply)

Hello,
Our software is using a TCP socket (AF_INET, SOCK_STREAM) to communicate with an Ethernet device. When we send a message, the message object writes itself in full onto the socket's stream buffer before the software invokes send() from socket.h.

spi_execute_with_args
SPI_EXECUTE_WITH_ARGS(3) PostgreSQL 9.2.7 Documentation SPI_EXECUTE_WITH_ARGS(3)
NAME
SPI_execute_with_args - execute a command with out-of-line parameters
SYNOPSIS
int SPI_execute_with_args(const char *command,
int nargs, Oid *argtypes,
Datum *values, const char *nulls,
bool read_only, long count)
DESCRIPTION
SPI_execute_with_args executes a command that might include references to externally supplied parameters. The command text refers to a
parameter as $n, and the call specifies data types and values for each such symbol. read_only and count have the same interpretation as in
SPI_execute.
The main advantage of this routine compared to SPI_execute is that data values can be inserted into the command without tedious
quoting/escaping, and thus with much less risk of SQL-injection attacks.
Similar results can be achieved with SPI_prepare followed by SPI_execute_plan; however, when using this function the query plan is always
customized to the specific parameter values provided. For one-time query execution, this function should be preferred. If the same command
is to be executed with many different parameters, either method might be faster, depending on the cost of re-planning versus the benefit of
custom plans.
ARGUMENTS
const char * command
command string
int nargs
number of input parameters ($1, $2, etc.)
Oid * argtypes
an array containing the OIDs of the data types of the parameters
Datum * values
an array of actual parameter values
const char * nulls
an array describing which parameters are null
If nulls is NULL then SPI_execute_with_args assumes that no parameters are null.
bool read_only
true for read-only execution
long count
maximum number of rows to return, or 0 for no limit
RETURN VALUE
The return value is the same as for SPI_execute.
SPI_processed and SPI_tuptable are set as in SPI_execute if successful.
