Open Directory in cc65

[TGB1718]

Is there a way to open a directory in cc65, in BASIC it's easy, some demo code below, but fopen in C uses :- fd=fopen(infile,"r");

ICAUX1 need to be 2 to open a directory, not sure this is supported ?, if not any examples using assembler would help.

 

thanks

 

I just want to be able to read the directory and display the contents.

 

DIM A$(18)
5 TRAP 1000
10 OPEN #1,2,0,"D:*.DAT"
20 GET #1,A:GET #1,A : REM throw away first 2 spaces
30 GOSUB 2000
90 ? A$
100 GOTO 20
1000 CLOSE #1
1010 END
2000 A$=""
2005 FOR I=1 TO 11
2010 GET #1,A
2020 A$(LEN(A$)+1)=CHR$(A)
2100 NEXT I
2110 GET #1,A: throw away size
2120 IF A<>155 THEN 2110: rem look for end of string
2130 RETURN

outputs :-

READY
RUN
PLAYERM DAT
UFO     DAT
TEMP    DAT
SPACE   DAT
REBOUND DAT
SPRITE  DAT
SP1     DAT
SP2     DAT
SP3     DAT
MISSILE DAT
M       DAT
SP0     DAT

No clue about CC65, but generally ICAUX1 beeds to be *6* to open a directory (bit 1 set beside bit 2 being set too).

Check dirent.h, you should be able to utilise opendir/readdir/closedir

Many thanks, I thought it would be in there somewhere, I'll give it a try

Gave it a try, just had to figure out a few things, but this works great

@Wrathchild many thanks again.

 

The printf's are like that to put space padded strings in 2 columns for formatting.

 

Here a sample in cc65

 

void directory(void)
{
    DIR *fd;
    char name[]="D:*.*";
    struct dirent *mydir;
    cls();
    gotoxy(0,0);
    fd = opendir(name);
    if(fd != NULL)
    {
        do
        {
            mydir = readdir(fd);
            if(mydir != 0)
            {
                printf("%s%*s",mydir->d_name,16-strlen(mydir->d_name)," ");
            }
            else
                break;
            mydir = readdir(fd);
            if(mydir != 0)
            {
                printf("%s%*s\n",mydir->d_name,16-strlen(mydir->d_name)," ");
            }
            else
                break;
        }while(1);
        closedir(fd);
    }
    gets(infile); // for debug
}
