debugging - 将 erlang 的梁文件转储到文件系统

Question

我有一个remsh正在工作的 Erlang 应用程序：

1> application:which_applications().
[{ssl,"Erlang/OTP SSL application","5.3.6"},
 {public_key,"Public key infrastructure","0.22.1"},
 {crypto,"CRYPTO","3.4.1"},
 {asn1,"The Erlang ASN1 compiler version 3.0.2","3.0.2"},
 {stdlib,"ERTS  CXC 138 10","2.2"},
 {kernel,"ERTS  CXC 138 10","3.0.3"}]

我的问题是：如何将梁文件保存到文件系统的另一个位置？

Answer 1

对于要保存的每个模块，调用code:get_object_code/1以将模块的目标代码作为二进制文件获取，然后用于file:write_file/2将该二进制文件保存到文件系统。
