C/C++从文件路径中取文件名

void* GetFilename(const char* fullpathname)

{

char* save_name, *pos;

int name_len;

name_len = strlen(fullpathname);

pos = fullpathname + name_len;

while(*pos != '\\' && pos != fullpathname)

pos --;

if(pos == fullpathname)

{

save_name = fullpathname+1;

return save_name;

}

name_len = name_len-(pos-fullpathname);

save_name = (char*) malloc(name_len+1);

memcpy(save_name,pos+1,name_len);

return save_name;

}
