(uint8 *) t represents a pointer converted to uint8_t type. Uint8 should be an unsigned 8-bit binary integer, which is actually an unsigned char type.

Forcibly convert the variable t type to uint8 * type, that is, to a pointer variable pointing to a variable of uint8 type.

Uint8_t: u is unsigned, int-shaped, and 8 occupies 8 bytes. _t is a universal suffix.

Specific definition: typedef unsigned int uint8 _ t; It's in < stdint.h & gt.

Extended data:

The corresponding *_t type of general plastics is:

1 byte uint8_t

2 bytes uint 16_t

4 bytes uint32_t

8 bytes uint64_t
