Name
       t_free - free a library structure

Syntax
       #include <xti.h>

       int t_free(ptr, struct_type)
       char *ptr;
       int struct_type;

Arguments
       ptr	 Points to one of the seven structure types described for

       struct_type
		 Identifies the type of that structure, which must be one of the following:

		 T_BIND_STR	     struct    t_bind;
		 T_CALL_STR	     struct    t_call
		 T_OPTMGMT_STR	     struct    t_optmgmt
		 T_DIS_STR	     struct    t_discon
		 T_UNITDATA_STR struct	  t_unitdata
		 T_UDERROR_STR	     struct    t_uderr
		 T_INFO_STR	     struct    t_info

		 Each of these structures is used as an argument to one or more transport functions.

Description
       The  function frees memory previously allocated by This function frees memory for the specified structure and also frees memory for buffers
       referenced by the structure.

       ---------------------------------------
       Parameters    Before Call   After Call
       ---------------------------------------
       ptr	     x		   /
       struct_type   x		   /
       ---------------------------------------

       The function checks the addr, opt, and udata fields of the given structure (as appropriate) and free the buffers  pointed  to  by  the  buf
       field  of the netbuf structure.	If buf is NULL, does not attempt to free memory.  After all buffers are freed, frees the memory associated
       with the structure pointed to by ptr.

       Results are undefined if ptr or any of the buf pointers points to a block of memory not previously allocated by

Return Values
       Upon successful completion, a value of 0 is returned. On failure,  a value of -1 is returned, and t_errno is set to indicate the error.

Diagnostics
       On failure, t_errno is set to one of the following:

       [TNOTSUPPORT]	   This function is not supported by the current implementation of XTI.

       [TSYSERR]	   A system error has occurred during execution of this function.

NAME

       t_free - free a library structure

SYNOPSIS

       #include <xti.h>

       int t_free(void *ptr, int struct_type);

DESCRIPTION

       This  routine is part of the XTI interfaces which evolved from the TLI interfaces. XTI represents the future evolution of these interfaces.
       However, TLI interfaces are supported for compatibility. When using a TLI routine that has the same name as an XTI routine,  the   tiuser.h
       header file must be used.  Refer to the	TLI COMPATIBILITY section for a description of differences between the two interfaces.

       The  t_free()  function frees memory previously allocated by t_alloc(3NSL). This function will free memory for the specified structure, and
       will also free memory for buffers referenced by the structure.

       The argument ptr points to one of the seven structure types described for t_alloc(3NSL), and struct_type identifies the type of that struc-
       ture which must be one of the following:

	      T_BIND	  struct  t_bind
	      T_CALL	  struct  t_call
	      T_OPTMGMT   struct  t_optmgmt
	      T_DIS	  struct  t_discon
	      T_UNITDATA  struct  t_unitdata
	      T_UDERROR   struct  t_uderr
	      T_INFO	  struct  t_info

       where each of these structures is used as an argument to one or more transport functions.

       The  function t_free() will check the addr, opt and udata fields of the given structure, as appropriate, and free the buffers pointed to by
       the buf field of the netbuf structure. If buf is a null pointer, t_free() will not attempt to free memory.  After all  buffers  are  freed,
       t_free() will free the memory associated with the structure pointed to by ptr.

       Undefined  results  will  occur	if  ptr  or  any  of  the  buf	pointers  points to a block of memory that was not previously allocated by
       t_alloc(3NSL).

RETURN VALUES

       Upon successful completion, a value of  0 is returned.  Otherwise, a value of  -1 is returned and t_errno is set to indicate an error.

VALID STATES

       ALL - apart from T_UNINIT.

ERRORS

       On failure, t_errno is set to the following:

       TNOSTRUCTYPE	       Unsupported struct_type requested.

       TPROTO		       This error indicates that a communication problem has been detected between XTI	and  the  transport  provider  for
			       which there is no other suitable XTI error (t_errno).

       TSYSERR		       A system error has occurred during execution of this function.

TLI COMPATIBILITY

       The  XTI  and  TLI interface definitions have common names but use different header files. This, and other semantic differences between the
       two interfaces are described in the subsections below.

   Interface Header
       The XTI interfaces use the header file, xti.h. TLI interfaces should not use this header.  They should use the header:

       #include <tiuser.h>

   Error Description Values
       The t_errno value that can be set by the XTI interface and cannot be set by the TLI interface is:

       TPROTO
