DESCRIPTION

Purpose

ESCAPE is a standard way of being nonstandard.  The single function can access any of the implementation-dependent escape functions, which might perform a nonstandard action or return nonstandard information. 

Each escape function has its own page in the reference manual.  The name of the page is escape_xx, where xx is replaced by the function identifer, e.g., escape_-2. 

In SunPHIGS, ESCAPE may be used to:

•  enforce synchronized error reporting
•  request an input event callback routine
