-.SH DESCRIPTION
-The
-.BR libsimple_malloczn (),
-.BR libsimple_enmalloczn (),
-and
-.BR libsimple_emalloczn ()
-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, where
-.I N
-is the product of
-.I n
-and all following arguments (which should have the type
-.BR size_t )
-up to the first 0;
-.I n
-must not be 0. 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_enmalloczn ()
-and
-.BR libsimple_emalloczn ()
-functions will terminate the process if the memory
-cannot be allocated, 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_enmalloczn ()
-function is used or
-.IR libsimple_default_failure_exit (3)
-if the
-.BR libsimple_emalloczn ()
-function is used.
-.PP
-The
-.BR libsimple_vmalloczn (),
-.BR libsimple_envmalloczn (),
-and
-.BR libsimple_evmalloczn ()
-functions are versions of the
-.BR libsimple_malloczn (),
-.BR libsimple_enmalloczn (),
-and
-.BR libsimple_emalloczn (),
-respectively, that use
-.B va_list
-instead of variadic arguments.
-.SH RETURN VALUE
-The
-.BR libsimple_vmalloczn (),
-.BR libsimple_envmalloczn (),
-.BR libsimple_evmalloczn (),
-.BR libsimple_malloczn (),
-.BR libsimple_enmalloczn (),
-and
-.BR libsimple_emalloczn ()
-functions return a pointer to the allocated memory
-upon success completion; otherwise the
-.BR libsimple_vmalloczn ()
-and
-.BR libsimple_malloczn ()
-functions return
-.B NULL
-and set
-.I errno
-it indicate the error, and the
-.BR libsimple_envmalloczn (),
-.BR libsimple_evmalloczn (),
-.BR libsimple_enmalloczn (),
-and
-.BR libsimple_emalloczn ()
-functions terminated the process.
-.SH ERRORS
-The
-.BR libsimple_vmalloczn (),
-.BR libsimple_malloczn ()
-function will fail for the reasons specified for the
-.BR malloc (3)
-and
-.BR calloc (3)
-functions, and if:
-.TP
-.B EINVAL
-.I n
-is 0.
-.PP
-The
-.BR libsimple_envmalloczn (),
-.BR libsimple_evmalloczn (),
-.BR libsimple_enmalloczn (),
-and
-.BR libsimple_emalloczn ()
-functions will terminate the process on failure.
