Hi,
Im use boost::process::child to create a mysql cli child process to 
import sql file.
Normally im use this command:
/usr/bin/mysql mysql -h127.0.0.1 -utestuser --password='!@#QWE123qwe' 
-P3306 --default-character-set=utf8mb4 --max-allowed-packet=1GB < 
/root/create_db.sql
It?s worked well in bash.
But when use boost::process::child, std_err report ERROR 1045 (28000): 
Access denied for user 'testuser'@'localhost' (using password: YES).
Is there any bugs in my code?
[...]
I have no experience with boost::process, only one idea:

Maybe the apostrophs around the password are normally eaten by the Linux 
shell, and you have to leave them out when building your arguments?

    // connection info
    args.push_back("-h127.0.0.1");
    args.push_back("-utestuser");
    args.push_back("--password=!@#QWE123qwe");    // <=
    args.push_back("-P3306");

Freundliche Grüße * Best regards * Met vriendelijke groeten * Meilleures 
salutations
