Base WG Resolution Ref: bwg97-001
Topic: Legacy Error returns

This is an approved Base Working Group Resolution for XSH Issue 5.

Last update: 09 October,1997

								97 #001


	Topic:			Legacy Error returns
	Relevant Sections:	Multiple
	Spec:			XSH Issue 5

Resolution Request:
Certain LEGACY routines do not have explicit error
returns and ENOSYS errors defined. 

The interfaces are minimally: getdtablesize
getpagesize re_comp re_exec , brk, sbrk.

Resolution Response
The intent of the legacy functions was not to change their
interface , thus where no explicit error returns were
previously defined, these cannot be introduced now.
The introduction to section 1.3 specifies the global
requirement that ENOSYS be set in errno.
The test suite can only check the setting of errno.
