106 Pascal 4.0 User’s Guide

The record in the example above has, by default, the same size and alignment

as the equivalent C record. Some records, though, are laid out differently

unless you use the -calign option.

The C main program,

StruChrMain.c

#include <stdio.h>

#include <string.h>

struct TVarLenStr {

int NBytes;

char a[25];

};

extern void StruChr(struct TVarLenStr *);

int main(void)

{

struct TVarLenStr vls;

char s25[25];

vls.NBytes = 0;

StruChr(&vls);

strncpy(s25, vls.a, vls.NBytes);

printf(" s25 = '%s' \n", s25);

printf(" strlen(s25) = %d \n", strlen(s25));

}

The commands to compile and

execute StruChr.p and

StruChrMain.c

hostname% pc -c StruChr.p

hostname% cc StruChr.o StruChrMain.c -lpc

hostname% a.out

s25='St. Petersburg'

strlen(s25) = 13

1 2 ... 125 126 127 128 129 130 131 132 133 134 135 ... 332 333
