+.SH DESCRIPTION
+The
+.BR libsimple_pvallocz (),
+.BR libsimple_enpvallocz (),
+and
+.BR libsimple_epvallocz ()
+functions allocate
+.I n
+bytes, rounded up to the next multiple of the page size,
+to the heap and return a pointer with an alignment of
+the page size 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_enpvallocz ()
+and
+.BR libsimple_epvallocz ()
+functions will terminate the process if the memory
+cannot be allocated of if the user tries 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_enpvallocz ()
+function is used or
+.IR libsimple_default_failure_exit (3)
+if the
+.BR libsimple_epvallocz ()
+function is used.
+.PP
+The
+.BR libsimple_enpvallocz ()
+and
+.BR libsimple_epvallocz ()
+functions behaviour is unspecified if
+.I n
+is 0.
+.SH RETURN VALUE
+The
+.BR libsimple_pvallocz (),
+.BR libsimple_enpvallocz (),
+and
+.BR libsimple_epvallocz ()
+functions return a pointer to the allocated memory
+upon success completion; otherwise the
+.BR libsimple_pvallocz ()
+function return
+.B NULL
+and set
+.I errno
+it indicate the error, and the
+.BR libsimple_enpvallocz ()
+and
+.BR libsimple_epvallocz ()
+functions terminated the process.
+.SH ERRORS
+The
+.BR libsimple_pvallocz ()
+function will fail if:
+.TP
+.B ENOMEM
+Enough memory could not be allocated.
+.PP
+The
+.BR libsimple_enpvallocz ()
+and
+.BR libsimple_epvallocz ()
+functions will terminate the process on failure.
