NAME

       x86_init, x86_cleanup - initialize and cleanup libdisasm

SYNOPSIS

       #include <libdis.h>

       typedef void (*DISASM_REPORTER)( enum x86_report_codes code,
               void * data, void * arg );

       int x86_init( enum x86_options options, DISASM_REPORTER reporter,
               void * arg);

       int x86_cleanup(void);

DESCRIPTION

       enum x86_options {
            opt_none= 0,
            opt_ignore_nulls=1, /* ignore sequences of > 4 NULL bytes */
            opt_16_bit=2,       /* 16-bit/DOS disassembly */
            opt_unknown
       };

       enum x86_report_codes {
               report_disasm_bounds,
               report_insn_bounds,
               report_invalid_insn,
               report_unknown
       };

EXAMPLES

       The following provides a skeleton for initializing and terminating
       libdisasm:

       void reporter( enum x86_report_codes code, void *data, void *arg ) {
               char * str = NULL;
               FILE *stream = (FILE *) arg;
               if (! stream ) stream = stderr;

               /* here would could examine the error and do something useful;
                * instead we just print that an error occurred */
               switch ( code ) {
                       case report_disasm_bounds:
                               str = "Attempt to disassemble RVA "
                                     "beyond end of buffer";
                               break;
                       case report_insn_bounds:
                               str = "Instruction at RVA extends "
                                     "beyond buffer";
                               break;
                       case report_invalid_insn:
                               str = "Invalid opcode at RVA";
                               break;
                       case report_unknown:
                               str = "Unknown Error";
                               break;
               }

               fprintf(stream, "ERROR ´%s:´ %p0, str, data);
       }

       int main( int argc, char **argv ) {
               x86_init(opt_none, reporter, stderr);

               /* disassembler code goes here */

               x86_cleanup();
       }
