💅 qmi_decode_struct_elem(9) ✨

💖 NAME

qmi_decode_struct_elem — okay bestie, this is a Kernel API Manual page, and it's literally about decoding elements of struct data type. No cap, that's the whole vibe: struct elements go in, decoded struct elements come out. 💖

✨ SYNOPSIS

int qmi_decode_struct_elem (const struct qmi_elem_info *ei_array , void
       *buf_dst , const void *buf_src , u32 elem_len , u32 tlv_len , int
       dec_level );

🧚 ARGUMENTS

• ei_array — the struct-info array that describes the struct element. It's giving "map of the struct," iykyk.
• buf_dst — the buffer where the decoded element gets stored. That's the destination, bestie.
• buf_src — the buffer holding the elements in QMI wire format. That's where the encoded data is chilling.
• elem_len — the number of elements to be decoded. Exactly that many, periodt.
• tlv_len — the total size of the encoded information corresponding to this struct element. It's the whole encoded package size for this one.
• dec_level — the depth of the nested structure from the main structure. Basically, how deep into the nesting we are.

🌸 DESCRIPTION

So here's the tea: this function decodes the "elem_len" number of elements in QMI wire format. Each one is "(tlv_len/elem_len)" bytes, and they get pulled from the source buffer "buf_src". Then the decoded elements are stored in the destination buffer "buf_dst". 🫶

The elements are of struct data type, which includes any C structure. Yes, any C structure — it's versatile like that. This function returns the number of bytes of decoded information.

🎀 RETURN

On success, you get the total size of the decoded data elements. 💖 On error, it returns a negative errno. So if the number is negative, that's your lil red flag — not a slay.
