Hi I tried uploading a file using libcurl to a FTP-SSL server running on windows. My libcurl client program runs on Solaris 2.9 The client program was basically the same example program ftpupload.c but with some additions done to include userid:passwd, SSL options and a custom CURLOPT_READFUNCTION The problem that i face is that the client program runs completely. However on the server's user home directory, the file uploaded has the name while-uploading.txt with 0 bytes in it. The curl version i am running on the client solaris machine is bash-2.05# curl --version curl 7.14.1 (sparc-sun-solaris2.9) libcurl/7.14.1 OpenSSL/0.9.8 zlib/1.1.3 Protocols: ftp gopher telnet dict ldap http file https ftps Features: IPv6 Largefile NTLM SSL libz bash-2.05# The sample curl client program is bash-2.05# cat ftpupload.c /***************************************************************************** * _ _ ____ _ * Project ___| | | | _ \| | * / __| | | | |_) | | * | (__| |_| | _ <| |___ * \___|\___/|_| \_\_____| * * $Id: ftpupload.c,v 1.7 2005/01/20 14:24:56 bagder Exp $ */ #include <stdio.h> #include <curl/curl.h> #include <sys/types.h> #include <sys/stat.h> #include <fcntl.h> #define TRUE 1 /* * This example shows an FTP upload, with a rename of the file just after * a successful upload. * * Example based on source code provided by Erick Nuwendam.
