mmap2

long mmap2(long start,
           int length,
           int prot,
           int flags,
           int fd,

malloc

MemoryBlock malloc(int length,

分配内存

Parameters:

length - 大小

runtime - true表示使用mmap按页大小分配，相应的调用MemoryBlock.free方法则使用munmap释放，false表示使用libc.malloc分配，相应的调用MemoryBlock.free方法则使用libc.free释放

mmap

UnidbgPointer mmap(int length,
                   int prot)

munmap

int munmap(long start,
           int length)

setErrno

void setErrno(int errno)

set errno

getLastErrno

int getLastErrno()

getMemoryMap

Collection<MemoryMap> getMemoryMap()

setMMapListener

void setMMapListener(MMapListener listener)

getMMapListener

MMapListener getMMapListener()
