<tag/Declaration/<tt/void __fastcall__ longjmp (jmp_buf buf, int retval);/
<tag/Description/The <tt/longjmp/ function restores a program context from the
data in <tt/buf/, which must have been set by a preceeding call to
<tt/<ref id="setjmp" name="setjmp">/. Program execution continues as if the
call to <tt/<ref id="setjmp" name="setjmp">/ has just returned the value
<tt/retval/.
<tag/Limits/
<itemize>
<item>If the parameter <tt/retval/ is zero, the function will behave as if it
was called with a value of one.
<item>The function is only available as fastcall function, so it may only
be used in presence of a prototype.

<tag/Description/The <tt/setjmp/ function saves the current context in <tt/buf/

returns zero.
<tag/Limits/
<itemize>
<item>The function is only available as fastcall function, so it may only

<item><tt/setjmp/ is actually a macro as required by the ISO standard.
