Hi there, I'm developing my application to access SFTP server with libssh2. And, I want to give an ability to access the SFTP server from multi-threads to the application, for example, downloading some files simultaneously.
I have some questions about how to use libssh2_sftp_* functions. (1) Are "libssh2_sftp_*" functions thread-safe? (2) If yes, what is a value to issue for each thread? Do I need to issue a sftp_session value issued by the libssh2_sftp_init() function for each thread? Or, Can I share the sftp_session value with all threads? That is, do I need to issue a sftp_handle value issued by the libssh2_sftp_open(dir) for each thread with the same value of the sftp_session? (3) If a lock (ex. mutex) is necessary, where I should apply the lock against my code? From the libssh2_sftp_init() calling to the reading file with the all libssh2_sftp_read() calling? Or, each API calling? (4) Is there any sample code to use libssh2 in the multi-threading environment? Thank you for your advice. -- Yoichiro Tanaka Email: yoich...@eisbahn.jp Blog: http://www.eisbahn.jp/yoichiro
