Hi,
No to VLAIS (Variable length array in structure). All known size
of arrays and structures.
My intent is to find a way to write a request for data (the
IOREQ.fc) to an application. The IOREQ is my message struct and
the c-code on the other end of the pipe use same struct to
identify request. to keep it backward compatible I need to keep
IOREQ.
The c-code application will switch out request and return the
answer with char[] of data using the (IOREQ.src) dlang's created
pipe. i.e. the pipes is oneway "streets"
The purpose is to port a c-application to use dlang with a web ui
Since I'm new to dlang but know c-code I need to ask stupid level
questions ;)
Also I'm experimenting on OS X but it is intended for linux x86
in production, for now.
Only requirement is the struct IOREQ as sending structure and
char[] as receiving structure, using FIFO pipe's. Outgoing pipe
is fixed named and returning is based on mypid().
In pseudo code (don't have any working code yet)
open pipe and if doesn't exist create it, to receiver
open own pipe for reading.
create ioreq *io;
create spec sized char buffer
point io to start of buffer
add request to io.fc
add return pipe to io.src
write in pipe
read pipe for answer, into char array
close pipe
disassemble response into various struct data depending on
request. Here I simply try by returning the sent ioreq and echo
out the fc and src.
