T_FREE(3N) (Networking Support Utilities) T_FREE(3N)
NAME
t_free - free a library structure
SYNOPSIS
#include <tiuser.h>
int tfree(ptr, structtype)
char *ptr;
int structtype;
DESCRIPTION
The t_free function frees memory previously allocated by
t_alloc. This function will free memory for the specified
structure, and will also free memory for buffers referenced
by the structure.
Ptr points to one of the six structure types described for
t_alloc, and struct_type identifies the type of that
structure which can 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.
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 [see intro(3)]

structure. If buf is NULL, 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.
On failure, t_errno may be set to the following:
[TSYSERR] A system error has occurred during execution
of this function.

DIAGNOSTICS
t_free returns 0 on success and -1 on failure and t_errno is
set to indicate the error.
