Hi:
I am a new user to FreeBSD.
When I use the following program,I expected the out put would be;
argv=aaa
argv=bbbb
argv=dd
argv=kkkk
but actually the output is
argv=
argv=bbbb
argv=dd
argv=kkkk
I don't where argv[0] was missing.
#include <string.h>
#include <stdio.h>
void main(){
char **ap, *argv[10],*inputstring; //[10]
int i;
strcpy(inputstring,"aaa\tbbbb\tdd\tkkkk");
for (ap = argv; (*ap = strsep(&inputstring, "\t")) != NULL;)
if (**ap != '\0')
if (++ap >= &argv[10])
break;
for(i=0;i<4;i++) printf("argv=%s\n",argv[i]);
}
>How-To-Repeat:
>Fix:
Sorry to use following method to fix the problem
#include <string.h>
#include <stdio.h>
void main(){
char **ap, *argv[10],*inputstring; //[10]
char s3[32];
int i;
strcpy(inputstring,"aaa\tbbbb\tdd\tkkkk");
i=0;
for (ap = argv; (*ap = strsep(&inputstring, "\t")) != NULL;)
{
if(i==0)
strcpy(s3,*ap);
i++;
if (**ap != '\0')
if (++ap >= &argv[10])
break;
}
strcpy(argv[0],s3);
for(i=0;i<4;i++) printf("argv=%s\n",argv[i]);
}
