Function tikv_jemalloc_sys::dallocx

source · 
pub unsafe extern "C" fn dallocx(ptr: *mut c_void, flags: c_int)
Expand description

Deallocates previously-allocated memory region referenced by ptr.

This makes the space available for future allocations.

§Safety

The behavior is undefined if:

  • ptr does not match a pointer earlier returned by the memory allocation functions of this crate, or
  • ptr is null, or
  • the memory region referenced by ptr has been deallocated.
