#72 reading zero bytes in readNlSock()

[Mikhail Tchernychev]

In the file bip-init.c, function

static int readNlSock
int sockFd, char *bufPtr, size_t buf_size, int seqNum, int pId)

when reading

    do {
    /* Receive response from the kernel */
    if ((readLen = recv(sockFd, bufPtr, buf_size - msgLen, 0)) < 0) {
        perror("SOCK READ: ");
        return -1;
    }

  // Need to check if zero bytes was read and break - this is my fix
    if(!readLen) {
        break;
    }

...

Thank you!
Mikhail

Hi Steve,

I feel flattered. I assume this is a mistake.

Anyway thanks for thinking of me!
Duane
