Hi all,
I am posting to this forum for the first time so please help in correcting any posting protocol errors.
I am stuck with a peculiar problem. I want to send a big term from a C process loaded as port program by a gen_server. I am receiving them in a gen_server using
Code: handle_info({Post, {data, Data}})
The port is opened as
Code: open_port({spawn, Executable}, [{packet, 4}, binary, exit_status, use_stdio]))
In the C process I am using Code: erl_format("{~w}",...) // and other variations Code: port_info(Port, input)
What might I be doing wrong? Any direction/help/suggestions will be highly appreciated.
BR/Bikram
NB: I tried to search the forum and did not find any. Please point me to original one is this is a duplicate post. |

Hi all,
Solved it finally.
It seems that C encoding code that was computing the length of binary encoded erlang term as 32 bit integer in network byte order was returning 0 bytes for any binary payload of greater than 0xFF. How silly!
Anyway, until next time then.
Thanks/Bikram |
