函数名称：fdt_getprop_by_offset

函数原型：const void *fdt_getprop_by_offset(const void *fdt, int offset, const char **namep, int *lenp)

返回类型：void

参数：

类型参数名称
const void *fdt
intoffset
const char **namep
int *lenp
457  prop等于fdt_get_property_by_offset_(fdt, offset, lenp)
458  如果非prop则返回:NULL
460  如果namep则
463  name等于fdt_get_string(fdt, Alignment helpers:* These helpers access words from a device tree blob. They're* built to work even with unaligned pointers on platforms (ike* ARM) that don't like unaligned loads and stores, & namelen)
465  如果非name则
466  如果lenp则lenp等于namelen
468  返回:NULL
470  namep等于name
474  如果fdt_version(fdt)小于0x10且offset加prop的长度的和取模8且Alignment helpers:* These helpers access words from a device tree blob. They're* built to work even with unaligned pointers on platforms (ike* ARM) that don't like unaligned loads and stores大于等于8则返回:data加4
477  返回:data
