Here is a short test program.

#include <string.h>
#include <regex.h>

int main()
{
        char *rexp="/\\*([^*]|\\*[^/])*\\*/";
        char *buf;
        struct re_pattern_buffer rexp_c;
        struct re_registers regs;
        int bs;

        memset(&rexp_c,0,sizeof(rexp_c));
        memset(&regs,0,sizeof(regs));

        buf="/*a\nb\nc*/\n";
        bs=strlen(buf);

        re_syntax_options=RE_NO_BK_VBAR|RE_NO_BK_PARENS;
        re_compile_pattern(rexp,strlen(rexp),&rexp_c);
        re_search_2(&rexp_c,buf,bs,0,0,0,bs,&regs,bs);

        return 0;
}
