[펌] Erlang BIF 만들기

steps

1. run configure

2. add your bifs to erts/emulator/beam/bif.tab

bif re:grep/2 bif re:compile/1

3. create a C file

erts/emulator/beam/erl_bif_re.c

4. add your C file to erts/emulator/<arch>/Makefile

RUN_OBJS = $(OBJDIR)/erl_bif_re.o \

5. implement your bifs by stealing bits from existing erl_bif_*.c files

?

1 2 3 4 5

BIF_RETTYPE re_grep_2(BIF_ALIST_2){   Eterm result;   result = magic_function();   BIF_RET(result); }

6. run make; make install

notes

• steps 0-3 need only be done once.

• note that if you add

?

1	bif re:grep/2

to bif.tab there should be a erl_bif_re.c that implements

?

1	BIF_RETTYPE re_grep_2(BIF_ALIST_2);
