Package linkname exports various private functions from the standard library
using the //go:linkname directive.
DON'T USE THIS IF YOU DON'T KNOW WHAT IT IS.
Also, it is a bad practice to use private functions from other packages, and it is UNSAFE and not protected by the Go 1 compatibility promise.

func Runtime_memclrNoHeapPointers ¶
Runtime_memclrNoHeapPointers clears n bytes starting at ptr.
Usually you should use typedmemclr. Runtime_memclrNoHeapPointers should be used only when the caller knows that *ptr contains no heap pointers because either:
*ptr is initialized memory and its type is pointer-free, or
*ptr is uninitialized memory (e.g., memory that's being reused for a new allocation) and hence contains only "junk".
Runtime_memclrNoHeapPointers ensures that if ptr is pointer-aligned, and n is a multiple of the pointer size, then any pointer-aligned, pointer-sized portion is cleared atomically. Despite the function name, this is necessary because this function is the underlying implementation of typedmemclr and memclrHasPointers. See the doc of memmove for more details.
The (CPU-specific) implementations of this function are in memclr_*.s.
func Runtime_procPin ¶
func Runtime_procPin() int
Runtime_procPin links to runtime.procPin. It pins current p, return pid.
DON'T USE THIS if you don't know what it is.
func Runtime_procUnpin ¶
func Runtime_procUnpin()
Runtime_procUnpin links to runtime.procUnpin. It unpins current p.
func Runtime_readUnaligned32 ¶
Runtime_readUnaligned32 reads memory pointed by p as a uint32 value. It performs the read with a native endianness.
It is copied from runtime.readUnaligned32 instead of linked to help inlining.
func Runtime_readUnaligned64 ¶
Runtime_readUnaligned64 reads memory pointed by p as a uint64 value. It performs the read with a native endianness.
It is copied from runtime.readUnaligned64 but instead of linked to help inlining.
func Runtime_startTheWorld ¶
func Runtime_startTheWorld()
func Runtime_stopTheWorld ¶
func Runtime_stopTheWorld()
Runtime_stopTheWorld links to runtime.stopTheWorld. It stops all P's from executing goroutines, interrupting all goroutines at GC safe points and records reason as the reason for the stop. On return, only the current goroutine's P is running.
func Runtime_stringHash ¶
func Runtime_sysAlloc ¶
Runtime_sysAlloc allocates memory off heap by calling runtime.sysAllocOS.
DON'T use this if you don't know what it does.
func Runtime_sysFree ¶
func Runtime_sysFree(mem []byte)
Runtime_sysFree frees memory allocated by Runtime_sysAlloc.
DON'T use this if you don't know what it does.
