Below is the trace excerpt picking up where I successfully executed
libssh2_sftp_open() command and then issued the stat command. You'll
notice the file name is:
/ADT00359/%25ADT00359%25ADT00359%25null%25DONE%25dmh_65l1h3006gntl7mu00027jpn
The file name has embedded % which I have expanded to their hexadecimal
representation (%25). The program has not problem with opening this file
and successfully reading the contents. For some reason it cannot return
the actual file size.

libssh2_sftp_read()!
<------END EXCERPT--------------->
The interesting lines of the program (basically example/sftp.c) which are
generating this output are:
sftp_handle =
libssh2_sftp_open(sftp_session, sftppath, LIBSSH2_FXF_READ, 0);
if (!sftp_handle) {
fprintf(stderr, "Unable to open file with SFTP: %ld\n",
libssh2_sftp_last_error(sftp_session));
goto shutdown;
}
fprintf(stderr, "libssh2_sftp_open() is done, get file information\n");
LIBSSH2_SFTP_ATTRIBUTES attrs;
rc = libssh2_sftp_stat_ex(sftp_session, sftppath, strlen(sftppath),
LIBSSH2_SFTP_LSTAT, &attrs );
if (rc<0)
{
fprintf(stderr, "error trying to fstat_ex, returned %d\n", rc);
}
else
{
fprintf(stderr, "Stat Data: RetCode=%d\n", rc);
fprintf(stderr, "Stat Data: Size=%llu\n", attrs.filesize);
fprintf(stderr, "Stat Data: Perm=%lx\n", attrs.permissions);
fprintf(stderr, "Stat Data: mtime=%lu\n", attrs.mtime);
fprintf(stderr, "Stat Data: mtime=%s\n",
asctime(localtime(&attrs.mtime)));
