.SH DESCRIPTION
The
.BR libsimple_enmalloc ()
and
.BR libsimple_emalloc ()
functions are wrappers for the
.BR malloc (3)
function, they allocate
.I n
uninitialised bytes to the heap and return a
pointer with an alignment of
.I alignof(max_align_t)
to the allocated memory. 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_enmalloc ()
and
.BR libsimple_emalloc ()
functions will terminate the process if the memory
cannot be allocated (or if
.I n
is 0 and
.BR malloc (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_enmalloc ()
function is used or
.IR libsimple_default_failure_exit (3)
if the
.BR libsimple_emalloc ()
function is used.
.PP
The
.BR libsimple_enmalloc ()
and
.BR libsimple_emalloc ()
functions behaviour is unspecified if
.I n
is 0.
.SH RETURN VALUE
The
.BR libsimple_enmalloc ()
and
.BR libsimple_emalloc ()
functions return a pointer to the allocated memory
upon success completion; otherwise the process is terminated.
.SH ERRORS
The
.BR libsimple_enmalloc ()
and
.BR libsimple_emalloc ()
functions will terminate the process on failure.
