module threads

// This module adds the necessary compiler flags for using threads.
// It is automatically imported by code that does `go func()` .
// See vlib/v/parser/pratt.v, search for ast.GoExpr .
// The goal is that programs, that do not use threads at all will not need
// to link to -lpthread etc.
// Note: on some platforms like Android, linking -lpthread is not needed too.
// See https://stackoverflow.com/a/31277163/1904615

$if !windows && !android {
	#flag -lpthread
}
