okay bestie, welcome to the Kernel API Manual — today's main character is fc_copy_buffer_to_sglist(9), and she is literally here to help. no cap, let's get into it. 💅

🎀 NAME 🎀

fc_copy_buffer_to_sglist — this routine copies the data of a buffer into a scatter-gather list (SG list). ✨

🌸 SYNOPSIS 🌸

u32 fc_copy_buffer_to_sglist (void *buf , size_t len , struct
       scatterlist *sg , u32 *nents , size_t *offset , u32 *crc );

🦋 ARGUMENTS 🦋

• buf — pointer to the data buffer. 🍓
• len — the byte-length of the data buffer.
• sg — pointer to the pointer of the SG list. 🫶
• nents — pointer to the remaining number of entries in the SG list.
• offset — pointer to the current offset in the SG list.
• crc — pointer to the 32-bit crc value. If crc is NULL, CRC is not calculated. 😭
