Hi,
So I have a huge array of structures, and when I run qsort to sort on a key, it zeros
out my entire array!!!! I have looked up every book I could find on C and I think
this is okay....but the results tell all!
Here is some code:
/* ---------------------------------------------- */
/* Data def. */
typedef struct uu_rec
{
char username[50];
int bytesSent;
int bytesRecieved;
char trans_date[30];
} UU_Record;
/* create the array */
UU_Record data_list[15000];
/* -----------------
* A bunch of code goes here
* to fill data_list with data
* -----------------*/
int my_strcmp(const void *a, const void *b)
{ return strcmp( ((UU_Record *)a)->username,((UU_Record*)b)->username);
}
/* Call the sort function */
qsort(data_list, 15000, sizeof(UU_Record), my_strcmp);
/* ----------------
* Now Data List
* is empty!!! WHY??
* ----------------/*
/* ---------------------------------------------- */
Thanks in advanced,
Ryan
