函数名称：fdt_get_name

函数原型：const char *fdt_get_name(const void *fdt, int nodeoffset, int *len)

返回类型：char

参数：

类型参数名称
const void *fdt
intnodeoffset
int *len
287  nh等于fdt_offset_ptr_(fdt, nodeoffset)
291  如果err等于Minimal sanity check for a read-only tree. fdt_ro_probe_() checks* that the given buffer contains what appears to be a flattened* device tree with sane information in its header.不等于0或err等于fdt_check_node_offset_(fdt, nodeoffset)小于0则转到:fail
295  nameptr等于name
297  如果fdt_version(fdt)小于0x10则
304  leaf等于strrchr - Find the last occurrence of a character in a string*@s: The string to be searched*@c: The character to search for
305  如果(leaf == NULL)则
306  err等于负FDT_ERR_BADVERSION: Given device tree has a version which* can't be handled by the requested operation. For* read-write functions, this may mean that fdt_open_into() is* required to convert the tree to the expected version.
307  转到:fail
309  nameptr等于leaf加1
312  如果len则len等于strlen(nameptr)
315  返回:nameptr
317  fail :
318  如果len则len等于err
320  返回:NULL
