Comparison of C-Language Environment terminology

The term signal is defined differently under C than under Language Environment, and you need to know the distinction to understand how C and Language Environment condition handling interact. Here is a comparison of the terminology Language Environment and C use to describe the same general idea:

• Using Language Environment services, you register a condition handler by using CEEHDLR, and you raise a condition by using CEESGL.
• Using C functions, you register a signal handler by using the signal() function, and you raise a signal using the raise() function.

  You can think of signal as the C term for a Language Environment condition. To simplify the following discussion, the term condition is used in place of signal.
