Hi Everyone
Is it possible someone can tell me how this code can be written to
change the pointer sent to it
in pow! using a VAR it will make a copy so the value can be changed but
I am unable to figure it out in C?
int main(void)
char *string;
file_reads(1,5,&string);
printf("%s \n",string);
return 0;
}
function from include file:
void file_reads(int handle,int length,char *dummy)
{
if ((dummy=(char *)malloc(length+1))==NULL){
puts("Error code here");
exit(1);
}
if((fread(dummy,sizeof(char),length,filehandle[handle]))!=length){
puts("Put error code here");
exit(1);
}
*(dummy+length)=0x00;
printf("%s\n",dummy);//it prints here fine as expected.
return;
}
thanks in advance
Steven Watson
