A program which merely calls \fBzxgmes\fR +to fetch and print the error message can be informative without compromising +portability (e.g., the default exception handlers do this). +.ih +RETURN VALUE +OK is returned for \fIos_exception\fR if no exception has occurred since +process startup or since the last call to \fBzxgmes\fR. If \fBzxgmes\fR +is called repeatedly following a single exception all calls after the first +will return OK. +.ih +NOTES +Any program which uses machine dependent exception codes is machine dependent. +The usage should be parameterized and documented in one of the system config +files. +.ih +SEE ALSO +zxwhen, zintpr +.endhelp -- cgit
