-## jerry_get_memory_limits
-
-**Summary**
-
-Gets configured memory limits of JerryScript.
-
-**Prototype**
-
-```c
-void
-jerry_get_memory_limits (size_t *out_data_bss_brk_limit_p,
-                         size_t *out_stack_limit_p);
-```
-
-- `out_data_bss_brk_limit_p` - out parameter, that gives the maximum size of data + bss + brk sections.
-- `out_stack_limit_p` - out parameter, that gives the maximum size of the stack.
-
-**Example**
-
-[doctest]: # ()
-
-```c
-#include "jerryscript.h"
-
-int
-main (void)
-{
-  jerry_init (JERRY_INIT_EMPTY);
-
-  size_t stack_limit;
-  size_t data_bss_brk_limit;
-  jerry_get_memory_limits (&stack_limit, &data_bss_brk_limit);
