import _ "unsafe" // When using cgo, call the C library for mmap, so that we call into // any sanitizer interceptors. This supports using the memory // sanitizer with Go programs. The memory sanitizer only applies to // C/C++ code; this permits that code to see the Go code as normal // program addresses that have been initialized. // To support interceptors that look for both mmap and munmap, // also call the C library for munmap.
