Subject: [PATCH 1/4] bdelta.h: make header C compatible
|
||
|
|
||
|
Exportaged names follow C calling. It's easier to
|
||
|
to pull library in in other languages.
|
||
|
|
||
|
Before patch:
|
||
|
$ nm libbdelta.so_ | grep bdelta_
|
||
|
0000000000002a00 T _Z11bdelta_passPvj
|
||
|
00000000000022c0 T _Z15bdelta_done_algPv
|
||
|
00000000000022b0 T _Z15bdelta_getErrorPv
|
||
|
0000000000002220 T _Z15bdelta_getMatchPvjPjS0_S0_
|
||
|
0000000000002190 T _Z15bdelta_init_algjjPFPvS_S_jjES_S_j
|
||
|
|
||
|
After patch:
|
||
|
$ nm libbdelta.so | grep bdelta_
|
||
|
00000000000022e0 T bdelta_done_alg
|
||
|
00000000000022d0 T bdelta_getError
|
||
|
0000000000002240 T bdelta_getMatch
|
||
|
00000000000021b0 T bdelta_init_alg
|
||
|
0000000000002a20 T bdelta_pass
|
||
|
|
||
|
Converted global constants to enum.
