Function rcpputils::fs::create_temp_directory

Function Documentation

path rcpputils::fs::create_temp_directory(const std::string &base_name, const path &parent_path = temp_directory_path())

Construct a uniquely named temporary directory, in “parent”, with format base_nameXXXXXX.

The output, if successful, is guaranteed to be a newly-created directory. The underlying implementation keeps generating paths until one that does not exist is found. This guarantees that there will be no existing files in the returned directory.

Parameters:

  • base_name – [in] User-specified portion of the created directory

  • parent_path – [in] The parent path of the directory that will be created

Throws:

std::system_error – If any OS APIs do not succeed.

Returns:

A path to a newly-created directory with base_name and a 6-character unique suffix
