.SH DESCRIPTION
The
.BR libsimple_mallocz (),
.BR libsimple_enmallocz (),
and
.BR libsimple_emallocz ()
functions are wrappers for the
.BR malloc (3)
and
.BR calloc (3)
functions, they allocate
.I n
bytes to the heap and return a pointer with an
alignment of
.I alignof(max_align_t)
to the allocated memory. The memory will be
initialised with zeroes if
.I clear
is a non-zero value. The function
.BR free (3)
shall be called with the returned pointer as
input when the allocated memory is no longer needed.
.PP
The
.BR libsimple_enmallocz ()
and
.BR libsimple_emallocz ()
functions will terminate the process if the memory
cannot be allocated (or if
.I n
is 0 and
.BR malloc (3)
and
.BR calloc (3)
returns
.B NULL
when it is used to allocate 0 bytes), by calling the
.BR libsimple_enprintf ()
and
.BR libsimple_eprintf ()
functions, respectively.
On failure, the process's exit value will be
.I status
if the
.BR libsimple_enmallocz ()
function is used or
.IR libsimple_default_failure_exit (3)
if the
.BR libsimple_emallocz ()
function is used.
.PP
The
.BR libsimple_enmallocz ()
and
.BR libsimple_emallocz ()
functions behaviour is unspecified if
.I n
is 0.
.SH RETURN VALUE
The
.BR libsimple_mallocz (),
.BR libsimple_enmallocz (),
and
.BR libsimple_emallocz ()
functions return a pointer to the allocated memory
upon success completion; otherwise the
.BR libsimple_mallocz ()
function return
.B NULL
and set
.I errno
it indicate the error, and the
.BR libsimple_enmallocz ()
and
.BR libsimple_emallocz ()
functions terminated the process.
.SH ERRORS
The
.BR libsimple_mallocz ()
function will fail for the reasons specified for the
.BR malloc (3)
and
.BR calloc (3)
functions.
.PP
The
.BR libsimple_enmallocz ()
and
.BR libsimple_emallocz ()
functions will terminate the process on failure.
