Thread: Would these two reference arguement functions give an error?

I wrote a shared library which has several functions. I am getting an unknown error when running my code.

Two of my functions may be called at the same time because I am running my code through another program. I've posted my code below.

Would char buffer[] and int *errnoOut cause an error, if the functions happen to update them simultaneously?

If so, what is the best way to deal with this?

Code:

// Send Data
int sendIPv6J(int sockfd, char buffer[], int *errnoOut) {
  int n;

	  n = send(sockfd, buffer, strlen(buffer) + 1, 0);

  if(n == -1) {

		      *errnoOut = errno;

       return(-1);

	   } else {

		      *errnoOut = 0;

       return(n);

	   }

}

// END



// Recv Data

int recvIPv6J(int sockfd, char buffer[], int maxBufferLength, int *errnoOut) {
  int n;

	  n = recv(sockfd, buffer, maxBufferLength, 0);

  if(n == -1) {

		    *errnoOut = errno;

    return(-1);

	  } else {

		    *errnoOut = 0;

    return(n);

	  }

}
// END

Thanks.

That makes sense.
