.SH NAME
libssh2_session_init_ex - initializes an SSH session object
.SH SYNOPSIS
#include <libssh2.h>

LIBSSH2_SESSION * 
libssh2_session_init_ex(LIBSSH2_ALLOC_FUNC((*myalloc)), LIBSSH2_FREE_FUNC((*myfree)), LIBSSH2_REALLOC_FUNC((*myrealloc)), void *abstract);

LIBSSH2_SESSION *
libssh2_session_init(void);

.SH DESCRIPTION
\fImyalloc\fP - Custom allocator function. Refer to the section on Callbacks 
for implementing an allocator callback. Pass a value of NULL to use the 
default system allocator.

\fImyfree\fP - Custom de-allocator function. Refer to the section on Callbacks 
for implementing a deallocator callback. Pass a value of NULL to use the 
default system deallocator.

\fImyrealloc\fP - Custom re-allocator function. Refer to the section on 
Callbacks for implementing a reallocator callback. Pass a value of NULL to 
use the default system reallocator.

\fIabstract\fP - Arbitrary pointer to application specific callback data. 
This value will be passed to any callback function associated with the named 
session instance.

Initializes an SSH session object. By default system memory allocators
(malloc(), free(), realloc()) will be used for any dynamically allocated memory
blocks. Alternate memory allocation functions may be specified using the
extended version of this API call, and/or optional application specific data
may be attached to the session object.

This method must be called first, prior to configuring session options or
starting up an SSH session with a remote server.
.SH RETURN VALUE
Pointer to a newly allocated LIBSSH2_SESSION instance, or NULL on errors.
