ECL_BLOCK_BEGIN
— C macro for block
ECL_BLOCK_BEGIN
(env,code) {
} ECL_BLOCK_END
;
ECL_BLOCK_BEGIN
establishes a block named code
that becomes visible for the Common Lisp code. This block can be used then as a target for cl_return
.
env
must be the value of the current Common Lisp environment, obtained with ecl_process_env
.
The C/C++ program has to ensure that the code in ECL_BLOCK_END
gets executed, avoiding a direct exit of the block via goto
or a C/C++ return
.
