+### `httplib_strdup( str );`
+
+### Parameters
+
+| Parameter | Type | Description |
+| :--- | :--- | :--- |
+|**`str`**|`const char *`|Pointer to the source string which must be duplicated|
+
+### Return Value
+
+| Type | Description |
+| :--- | :--- |
+|`char *`|Pointer to the duplicate, or NULL if an error occured|
+
+### Description
+
+The function `httplib_strdup()` duplicates a NUL terminated string to a new string. The duplicate is stored in a newly allocated block of memory. The function is equivalent to the Posix `strdup()` function with the difference that the LibHTTP memory allocation functions are used which allow for tracking of allocation requests and memory leaks through a monitor hook.
+
+If the duplicate of the string is no longer used, the allocated memory should be returned to the heap with a call to [`httplib_free()`](httplib_free.md).
+
+If the function fails the value `NULL` is returned, otherwise a pointer to the duplicate.
