Yes, it's installed. Didn't quite the fit the bill in this case, but
perhaps I can find other uses for it. At any rate, I'm giving up on
this. My C program can launch dialog and create the listing, but it
can't check the return value. I have to admit defeat in this case.
Oh, well. I have other windows and dos apps that I am going to try to
recreate, so, next!
Here's the final source code for the C program in case anyone ever
wants to attempt this.
#include <unistd.h>
#include <stdio.h>
#include <dirent.h>
#include <string.h>
#include <sys/stat.h>
#include <stdlib.h>
void newstrcat(char * dest, char * source);
void printdir(char * dir);
void inttostr(char * x);
char curdir[266] = "";
char cmdline[32000] = "dialog --menu \"Choose folder\" 20 30 14";
int counter = 0;
int main()
{
int result;
getcwd(curdir, 265);
printdir(curdir);
system(cmdline);
}
void printdir(char * dir)
{
DIR * dp;
char num[20] = "";
char twobytes[2]="";
struct dirent * entry;
struct stat statbuf;
if((dp=opendir(dir)) == NULL)
{
fprintf(stderr, "Failed.\n");
return;
}
while((entry=readdir(dp))!= NULL)
{
lstat(entry->d_name, &statbuf);
if(S_ISDIR(statbuf.st_mode))
{
counter++;
newstrcat(cmdline," ");
sprintf(num, "%i ", counter);
newstrcat(cmdline,num);
strcpy(num,"");
newstrcat(cmdline, entry->d_name);
}
}
closedir(dp);
} // end of printdir()
void newstrcat(char * dest, char * source)
{
if ((strlen(dest) + strlen(source)) >= 32000)
{
fprintf(stderr, "Failed.\n");
exit(0);
}
else
{
strcat(dest,source);
}
}
