name: duk_require_uint

proto: |
  duk_uint_t duk_require_uint(duk_context *ctx, duk_idx_t idx);

stack: |
  [ ... val! ... ]

summary: |
  <p>Like <code><a href="#duk_get_uint">duk_get_uint()</a></code>,
  but throws an error if the value at <code>idx</code> is not a number
  or if the index is invalid.</p>

  <!--
  <p>The number is coerced as for <code><a href="#duk_get_uint">duk_get_uint()</a></code>
  with only numeric inputs allowed.</p>
  -->

example: |
  printf("unsigned int value: %lu\n", (unsigned long) duk_require_uint(ctx, -3));
