The following example copies the string “———-“<\/b> into the permstring<\/i> variable.<\/p>\n
…
static char permstring[11];

The following example allocates space for a key using malloc<\/i>() then uses strcpy<\/i>() to place the key there. Then it allocates space for data using malloc<\/i>(), and uses strcpy<\/i>() to place data there. (The user-defined function dbfree<\/i>() frees memory previously allocated to an array of type struct element *<\/b>.)<\/p>\n
