    <p>I've been trying to solve this bsearch homework problem for awhile now. I try using my code to first search for one entry like so:</p> <pre><code>int Compare(const void *a, const void *b); void SortStudents(char *studentList[], size_t studentCount) { qsort(studentList, studentCount, sizeof(studentList[0]), Compare); } int Compare(const void *a, const void *b) { return (strcmp(*(char **)a, *(char **)b)); } char *SearchList(char *key, char *list[], size_t num) { char **value = bsearch(&amp;key, list, num, sizeof(list[0]), Compare); return (value == 0 ? 0 : *value); } /*Determines which registrants did not attend the first meeting by searching for registrants that are not in attendees set. */ void DisplayClassStatus( const char *registrants[], size_t registrantCount, const char *attendees[], size_t attendeeCount) { char *missedFirstMeeting = SearchList((char *)registrants[0], (char **)attendees, attendeeCount); } </code></pre> <p>My missedFirstMeeting seems to work in calling out a single value properly, but when I try to repeatedly call my SearchList function in a loop like so:</p> <pre><code>for (int i = 0; i &lt; attendeeCount; i++) { *missedFirstMeeting = SearchList((char *)registrants[i], (char **)attendees, attendeeCount); } </code></pre> <p>I get a segmentation fault error. To me it seems like I am doing the same thing, but just repeatedly calling the SearchList(), but obviously something is wrong that I do not see since I get that segmentation fault error. Any ideas? Thanks.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
