Does initilizing a struct with {0} works? 1

[BTCMan]

Recently I saw a code that initilizes a struct using {0} .My question is if this works for all elements of the struct or just the 1st one. Example:

.H File:

typedef struct
{
UINT32 size;
UINT16 num1;
UINT8 * p_buffer;
} MY_RECORD;

--------------
.C File:

...
MY_RECORD my_var = {0};

I believe the safest way to initialize the whole struct is:

memset(&my_var, 0, sizeof(MY_RECORD));

It works for all elements of the struct, and all unspecified members of the struct will be initialised with a 0 of the appropriate type (see next comment).

It's also a better way than using memset.

All-bits-zero is not necessarily a NULL pointer, nor floating point 0.0.
