You need to do this call: LIBSSH2_SFTP_ATTRIBUTES fileinfo; LIBSSH2_SESSION *session; ........ session = libssh2_session_init(); sftp_session = libssh2_sftp_init(session); status= status=libssh2_sftp_stat(sftp_session,"/tmp/myfile",&fileinfo); If status=0 then "/tmp/myfile" exists. ________________________________ From: [] On Behalf Of royconejo Sent: Friday, 24 July 2009 1:15 PM To: Subject: libssh2_sftp_open() error values Hello, How could I know if a given file exists over SFTP? requesting directory contents in not a good choice (I suppose) because there'll be hundreds of files and retrieving and searching in that list will be way slower than just trying to open the file, as one could do in the local filesystem (for example with fopen, open, etc) well, libssh2_sftp_open() returns NULL whenever it fails, but how could I discern if it was because of the ? Shoud I always expect an errno to be set, even when there was no connection error? perhaps ERROR_NONE since there was no real error apart from the file not being there? And shoud I expect any reliable behaviour when my local or remote machine lost connection? perhaps LIBSSH2_ERROR_SOCKET_SEND when I unplug my local machine or LIBSSH2_ERROR_SOCKET_TIMEOUT when the remote host fails? (Perhaps I'm a little confused and things are not that easy =p) Thanks in advance =)! *************************************************************** This message is intended for the addressee named and may contain confidential information.
