I found an old (short) program that uses dfind() and dnext().  It is
probably not bulletproof but should illustrate the above functions.

#include <dos.h>

void PrintDosError(int error);

char path[FMSIZE];

int main(int argc, char *argv[])
{
    int error;
    struct FILEINFO *info;
    int index, size;

    if (argc == 1) {
        printf("usage: %s <pattern>\n",argv[0]);
        exit(10);
    }

    info = (struct FILEINFO *)malloc(sizeof(struct FILEINFO));
    if (info == NULL) {
        printf("No memory.\n");
        exit(10);
    }

    for (index = 1; index < argc; index++) {

        printf("\nMatching: %s\n",argv[index]);
        printf("--------------------------\n");
        size = stcgfp(path,argv[index]);

        error = dfind(info,argv[index],1);
        while (error == 0) {

            if (size != 0) {
                printf("%s",path);
                if (path[size-1] != ':')
                    printf("/");
            }

            printf("%s",&(info->fib_FileName));
            if (info->fib_DirEntryType > 0)
                printf(" (dir)\n");
            else
                printf("\n");

            error = dnext(info);
        }

        if ( _OSERR != 0) {
            PrintDosError(_OSERR);
            printf("%s\n",argv[index]);
        }
    }

    return 0;

}

void PrintDosError(int error)
{
    extern int os_nerr;
    int index = 0;

    while (os_errlist[index].err_no <= os_nerr) {
        if (os_errlist[index].err_no == error) {
            printf("%s: ",os_errlist[index].msg);
            return;
        }
        index++;
    }

    printf("Unknown DOS Error: ");
}
