I got some errors

[CloudFeng]

using this project some errors in my environment

environment

• vs 2013
• 64bit

errors

1. add a line code in stocketpair.h

#pragma comment(lib, "Ws2_32.lib")

1. in main.c

thread_t thread;
socket_t sockets[2];

error: this declaration has no storage class or type specifier
after changed:

HANDLE thread;
SOCKET sockets[2];

1. in read_bytes function

total += recv(sockets[1], &buf[total], (int)(numbytes - total), 0);

argument of type "char (*)[81920]" is incompatible with parameter of type "char *"
buf is a point to point, why use &buf[total].
After changed:

total += recv(sockets[1], buf[total], (int)(numbytes - total), 0);

build and result

When build this project, then call init[] in q thread,sometime it said:wsfull;
sometime it crached. I don't know why, now I try to solve it.Could have some one face this problem? Thanks.

I'll install VS 2013 and have a look into the build errors.

I solve the errors which I faced

• in stocketpair.h file
  add #pragma comment(lib, "ws2_32.lib")

#ifdef WIN32
# include <ws2tcpip.h>  /* socklen_t, et al (MSVC20xx) */
#pragma comment(lib, "ws2_32.lib")
# include <windows.h>
# include <io.h>
#else
# include <sys/types.h>
# include <sys/socket.h>
# include <errno.h>
#endif

• I changed read_bytes and recieve_data functions, as followed

// read_bytes:read data from sockets[1]
void read_bytes(size_t numbytes, char buf[BUFFER_SIZE])
{
    int total = 0;
    do {
        total += recv(sockets[1], &buf[total], (int)(numbytes - total), 0);
    } while (total < numbytes);
}

K recieve_data(I x)
{
    static char buf[BUFFER_SIZE];
    read_bytes(sizeof(int), buf);
    int tnamesize = 0;
    memcpy(&tnamesize, buf, sizeof(int));
    read_bytes(tnamesize, buf);
    buf[tnamesize] = '\0';
    K tname = ks(buf);
    read_bytes(sizeof(J), buf);
    J size = 0;
    memcpy(&size, buf, sizeof(J));
    read_bytes(size, buf);
    K bytes = ktn(KG, size);
    memcpy(kG(bytes), &buf, (size_t)size);
    K result = k(0, ".u.upd", tname, d9(bytes), (K)0);
    r0(bytes);
    if (result != 0) {
        r0(result);
    }
    return (K)0;
}

• in run.q file, I also mended some code.Just delete

`g# / table attribute, it costs lots of memory

• BYW, I delete time colnum, as follow. However, it does work, the result is
  empty table.

trade:([]sym:symbol$(); exg:`symbol$(); size:(); volume:(); sequence:(); price:(); cond:());
.u.upd:{[t;x] insert[t] each 'flip x; }

use the raze function.
