WSPutByteArray (C Function)

int WSPutByteArray(WSLINK link,const unsigned char *a,const int *dims,const char **heads,int d)

puts an array of integers in the range 0255 to the WSTP connection specified by to form a depth- array with dimensions .


  • The array must be laid out in memory like a C array declared explicitly as .
  • If is given as NULL, the array will be assumed to have head List at every level.
  • The length of the array at level is taken to be .
  • WSPutByteArray() returns 0 in the event of an error, and a nonzero value otherwise.
  • Use WSError() to retrieve the error code if WSPutByteArray() fails.
  • WSPutByteArray() is declared in the WSTP header file wstp.h.

#include "wstp.h"

/* send a list of integers in the range 0-255 to a link */

void f(WSLINK lp)
    unsigned char array[10][5][3][4];
    long dims[4];
    int i;

    for(i = 0; i < 600; i++)
        *((unsigned char *)array + i) = i;

    dims[0] = 10;
    dims[1] = 5;
    dims[2] = 3;
    dims[3] = 4;

    if(! WSPutByteArray(lp, (unsigned char *)array, (long *)dims, (char **)0, 4))
        { /* unable to send array of integers to lp */ }
