alibNot

alibNot

Applies the ~ operator element-wise to scalar or array argument. The PV-WAVE API for this routine is the operator NOT.

Prototypes

void alibNotb( wvlong n, UCHAR *p, UCHAR *r )

void alibNots( wvlong n, short *p, short *r )

void alibNoti( wvlong n, int *p, int *r )

void alibNotl( wvlong n, wvlong *p, wvlong *r )

Parameters

n — (Input) The number of elements in the source array.

*p — (Input) The n-element source array.

*r — (Input/Output) The n-element destination array. On return, r[i] = ~p[i]. This operation can be done in-place (r can equal p).

Example

#include <stdio.h>

#include <stdlib.h>

#include <math.h>

#include "alib.h"

void main() {

   /* make up some input data for the examples */

   UCHAR b0[9] = {0,1,2,3,4,5,6,7,8};

   /* make an output array */

   UCHAR *b;

   b = (UCHAR*)malloc(9*sizeof(UCHAR));

   printf( "\n\n show the input array b0" );

      alibPrintArrayb( 1, 1, 1, 9, b0, NULL );

   printf( "\n\n put the 'bitwise not' of array b0 into array b" );

      alibinit( NULL, NULL, NULL, NULL );

      alibNotb( 9, b0, b );

      alibPrintArrayb( 1, 1, 1, 9, b, NULL );

   printf( "\n\n now do the same operation in-place on b0" );

      alibNotb( 9, b0, b0 );

      alibPrintArrayb( 1, 1, 1, 9, b0, NULL );

Output:

 show the input array b0

   0   1   2   3   4   5   6   7   8

 put the 'bitwise not' of array b0 into array b

 255 254 253 252 251 250 249 248 247

 now do the same operation in-place on b0
