+DESCRIPTION
+<<dprintf>> and <<vdprintf>> allow printing a format, similarly to
+<<printf>>, but write to a file descriptor instead of to a <<FILE>>
+stream.
+
+The functions <<_dprintf_r>> and <<_vdprintf_r>> are simply
+reentrant versions of the functions above.
+
+RETURNS
+The return value and errors are exactly as for <<write>>, except that
+<<errno>> may also be set to <<ENOMEM>> if the heap is exhausted.
+
+PORTABILITY
+This function is originally a GNU extension in glibc and is not portable.
+
+Supporting OS subroutines required: <<sbrk>>, <<write>>.
