VSI OpenVMS Forum

Hi All

I get the following:

rumba-jj) cc/vers
VSI C x86-64 X7.4-843 (GEM 50XB9) on OpenVMS x86_64 V9.2-1
rumba-jj) ty test.c
#include <stdio.h>
#include <stdlib.h>
int main()
{
#pragma pointer_size 64
int* i = (int*) malloc( 80 );

#pragma pointer_size 32
int* i2 = (int*) malloc( 80 );
printf( "%u %u" , i , i2 );
return 0;
}

Looks like the #pragma pointer_size is ignored. I get the same on IA64. What do I do wrong?

Try this: This pragma changes the type of pointers but does not cause the correct function to be substituted.

Thanks, that helps
