NAME
tfree - free a library structure
SYNOPSIS
#include <sys/tiuser.h>
int tfree(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 structure, 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 struc-
ture (as appropriate), and free the buffers pointed to by the buf
field of the netbuf 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.
DIAGNOSTICS
tfree returns 0 on success and -1 on failure and terrno is set to
indicate the error.
