+.SH DESCRIPTION
+.B usrtc_init
+and
+.B usrtc_create
+are used to initialize a new usrtc core structure. The difference is
+.B usrtc_create
+will allocate
+.B usrtc_t
+structure via
+.B malloc()
+function, but
+.B usrtc_init
+expect already allocated structure. Argument
+.B impl
+is used to point the type of search data structure used for this particular usrtc core structure. Possible values are:
+.br
+.B * USRTC_LIST:
+Linked list
+.br
+.B * USRTC_BST:
+Binary search tree
+.br
+.B * USRTC_REDBLACK:
+Redblack tree
+.br
+.B * USRTC_SPLAY:
+Splay tree
+.br
+.B * USRTC_AVL:
+AVL tree
+.br
+.B maxcount
+argument is pointing to a max amount of the nodes within a search data structure.
+.B compare
+is a pointer to a compare function.
+.br
+.B usrtc_destroy
+is used to destroy (free) usrtc core structure. This function must be used only for structures allocated via
+.B usrtc_create
+function.
+.br
+.SH RETURN VALUE
+Valid pointer to a newly allocated and initialized core structure, otherwise
+.B NULL.
+.br
+.SH BUGS
+Not known yet.
+.br
+.SH EXAMPLE
+.br
+.SH RATIONALE
+Using functions
+.B usrtc_create
+and
+.B usrtc_destroy
+is deprecating.
