Function Documentation

◆ generate_password()

bool generate_password ( char *  password,
int  size 
)

◆ initialize_create_data_directory()

bool initialize_create_data_directory ( const char *  data_home)

Create the data directory.

Creates the data directory when –initialize is specified. The directory is created when it does not exist. If it exists, is empty and the process can write into it no action is taken and the directory is accepted. Otherwise an error is thrown.

Parameters
