SH DESCRIPTION
These routines allocate and free memory.
On failure, they print an error message and call
IR sysfatal
(from
IR perror (2)).
They do not return.
PP
I Vtbrk
returns a pointer to a new, permanently allocated block of at least
I size
bytes.
PP
IR Vtmalloc ,
IR vtrealloc ,
and
I vtstrdup
are like
IR malloc ,
IR realloc ,
and
IR strdup ,
but, as noted above, do not return on error.
I Vtmallocz
is like
I vtmalloc
but zeros the block before returning it.
Memory allocated with all four should be freed with
I vtfree
when no longer needed.
