I thought I had the problem solved (after reading out of 3 books to get this
far), but the following fseek() function still does not work. The information
I wish to remove from the database file is still present. Any more idea's as to what I should try next, would be appreciated.
/* remove a name from the list */
void delete()
{
FILE *fptr;
char name[40];
struct addr addr_info;
long file_pos;
if((fptr=fopen("maillist.dbf","r+b"))==NULL)
{
fprintf(stderr,"Can't open, name not found.\n");
return;
}
printf("\n\n\n\n\n\n\t\t\tName your looking for? ");
gets(name);
while(!feof(fptr))
{
file_pos = ftell (fptr);
fread(&addr_info,sizeof(struct addr),1,fptr);
if(!strcmp(addr_info.name, name))
{
printf("\n\n\n\n\n\n\t\t\t\t%s\n", &addr_info.name);
printf("\t\t\t\t%s\n", &addr_info.street);
printf("\t\t\t\t%s\n", &addr_info.city);
printf("\t\t\t\t%s\n", &addr_info.state);
printf("\t\t\t\t%s\n", &addr_info.zip);
printf("\n\t\tIs this the name you want to remove? (Type 'y' or 'n'): ");
while(getche() == 'y')
{
addr_info.delete='y';
if(fseek(fptr, file_pos, SEEK_SET));
fwrite(&addr_info,(long) sizeof(struct addr),1,fptr);
clrscr();
return;
}
}
}
fclose(fptr);
}
