NAME¶
x86_init, x86_cleanup - initialize and cleanup libdisasmSYNOPSIS¶
#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 terminatinglibdisasm:
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();
}
