I am using the built in qsort to sort an array of structs. But after the call to qsort the last element in the array seems to have had its value that I am sorting by set to empty.
Here is my code...
int numEntries = 5;
TvEntry* entries[numEntries]; //create array
//Entries get added to the array here...
qsort( *entries, numEntries, sizeof(TvEntry*), &compareByName ); //sort
displayAll( entries, numEntries ); //display
//here is my sort method
int compareByName( const void* val1, const void* val2 )
{
const TvEntry* entry1 = (TvEntry*)val1;
const TvEntry* entry2 = (TvEntry*)val2;
return strcasecmp( entry1->title, entry2->title );
}
//here is my display method
void displayAll( TvEntry* entries[], int length )
{
if( entries == NULL )
{
printf( "List is empty\n" );
}
else
{
int i = 0;
for( i = 0; i < length; i++ )
{
printf( "ENTRY: %s\n", entries[i]->title );
}
}
}
I should mention that if i comment out the line which calls qsort then all entries are displayed correctly but when qsort is called then the entries are all displayed (Not Sorted) and printing a blank value for title for the last entry.
