t_free(3N) NETWORK FUNCTIONS t_free(3N)
NAME
tfree - free a library structure
SYNOPSIS
#include <tiuser.h>
int tfree(ptr, structtype)
char *ptr;
int structtype;
DESCRIPTION
The tfree function frees memory previously allocated by
talloc. 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
talloc, and structtype identifies the type of that struc-
ture, which can be one of the following:
TBIND struct tbind
TCALL struct tcall
TOPTMGMT struct toptmgmt
TDIS struct tdiscon
TUNITDATA struct tunitdata
TUDERROR struct tuderr
TINFO struct tinfo
where each of these structures is used as an argument to one
or more transport functions.
tfree 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, tfree will not attempt to free
memory. After all buffers are freed, tfree 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 talloc. On failure, terrno may be set to the
following:
[TSYSERR] A system error has occurred during execution
of this function.
