+.SH DESCRIPTION
+Adds a known host to the collection of known hosts identified by the 'hosts'
+handle.
+
+\fIhost\fP is a pointer the host name in plain text or hashed. If hashed, it
+must be provided base64 encoded. The host name can be the IP numerical address
+of the host or the full name.
+
+If you want to add a key for a specific port number for the given host, you
+must provide the host name like '[host]:port' with the actual characters '['
+and ']' enclosing the host name and a colon separating the host part from the
+port number. For example: \&"[host.example.com]:222".
+
+\fIsalt\fP is a pointer to the salt used for the host hashing, if the host is
+provided hashed. If the host is provided in plain text, salt has no meaning.
+The salt has to be provided base64 encoded with a trailing zero byte.
+
+\fIkey\fP is a pointer to the key for the given host.
+
+\fIkeylen\fP is the total size in bytes of the key pointed to by the \fIkey\fP
+argument
+
+\fIcomment\fP is a pointer to a comment for the key.
+
+\fIcommentlen\fP is the total size in bytes of the comment pointed to by the \fIcomment\fP argument
+
+\fItypemask\fP is a bitmask that specifies format and info about the data
+passed to this function. Specificly, it details what format the host name is,
+what format the key is and what key type it is.
+
+The host name is given as one of the following types:
+LIBSSH2_KNOWNHOST_TYPE_PLAIN, LIBSSH2_KNOWNHOST_TYPE_SHA1 or
+LIBSSH2_KNOWNHOST_TYPE_CUSTOM.
+
+The key is encoded using one of the following encodings:
+LIBSSH2_KNOWNHOST_KEYENC_RAW or LIBSSH2_KNOWNHOST_KEYENC_BASE64.
+
+The key is using one of these algorithms:
+LIBSSH2_KNOWNHOST_KEY_RSA1, LIBSSH2_KNOWNHOST_KEY_SSHRSA or
+LIBSSH2_KNOWNHOST_KEY_SSHDSS.
+
+\fIstore\fP should point to a pointer that gets filled in to point to the
+known host data after the addition. NULL can be passed if you don't care about
+this pointer.

+Returns a regular libssh2 error code, where negative values are error codes

+The key is encoded using one of the following encodings:

+
+\fIknownhost\fP if set to non-NULL, it must be a pointer to a 'struct

+host that matches or partially matches.
+.SH RETURN VALUE

+.fi
+
+You will find a full set of defines and macros to identify flags and
+permissions on the \fBlibssh2_sftp.h\fP header file, but some of the
+most common ones are:
+
+To check for specific user permissions, the set of defines are in the
+pattern LIBSSH2_SFTP_S_I<action><who> where <action> is R, W or X for
+read, write and excutable and <who> is USR, GRP and OTH for user,
+group and other. So, you check for a user readable file, use the bit
+\fILIBSSH2_SFTP_S_IRUSR\fP while you want to see if it is executable
+for other, you use \fILIBSSH2_SFTP_S_IXOTH\fP and so on.
+
+To check for specific file types, you would previously (before libssh2
+1.2.5) use the standard posix S_IS***() macros, but since 1.2.5
+libssh2 offers its own set of macros for this functionality:
+.IP LIBSSH2_SFTP_S_ISLNK
+Test for a symbolic link
+.IP LIBSSH2_SFTP_S_ISREG
+Test for a regular file
+.IP LIBSSH2_SFTP_S_ISDIR

-this option, and a typical "release build" might not.

+.SH DESCRIPTION
+libssh2_trace_sethandler installs a trace output handler for your application.
+By default, when tracing has been switched on via a call to libssh2_trace(),
+all output is written to stderr.  By calling this method and passing a
+function pointer that matches the libssh2_trace_handler_func prototype,
+libssh2 will call back as it generates trace output.  This can be used to
+capture the trace output and put it into a log file or diagnostic window.
+This function has no effect unless libssh2 was built to support this option,
+and a typical "release build" might not.
+
+\fBcontext\fP can be used to pass arbitrary user defined data back into the callback when invoked.
+.SH AVAILABILITY
+Added in libssh2 version 1.2.3
