用char *malloc(unsigned size)函数向系统申请一次内存空间（如size=1000，单位为字节），

用首次适应法

addr = (char *)fmalloc(unsigned size) 和

ffree(unsigned size,char * addr)

　　或用循环首次适应法

addr = (char *)lmalloc(unsigned size) 和

lfree(unsigned size,char * addr)

模拟UNIX可变分区内存管理，实现对该内存区的分配和释放管理。

-With char* malloc (unsigned size) to apply a function to the system memory space (for example, size = 1000, measured in bytes), with the first law to adapt to addr = (char*) fmalloc (unsigned size) and ffree (unsigned size, char* addr) or the first cycle to adapt to law addr = (char*) lmalloc (unsigned size) and lfree (unsigned size, char* addr) variable partition simulation UNIX memory management, the realization of the memory allocation and release management .
