Description

WriteHeapDump writes a description of the heap and the objects in it to the given file descriptor.

WriteHeapDump suspends the execution of all goroutines until the heap dump is completely written. Thus, the file descriptor must not be connected to a pipe or socket whose other end is in the same Go process; instead, use a temporary file or network socket.

The heap dump format is defined at https://golang.org/s/go15heapdump.
