rmi_read_block(9)

💅 rmi_read_block(9) 🎀

Okay bestie, welcome to the Kernel API Manual entry for rmi_read_block(9). It’s giving “read a block of bytes,” and honestly? Iconic.

🌸 NAME 🌸

rmi_read_block — read a block of bytes. That’s the whole name. Slay.

✨ SYNOPSIS ✨

int rmi_read_block (struct rmi_device *d , u16 addr , void *buf , size_t
       len );

🎀 ARGUMENTS 🎀

• d — Pointer to an RMI device. Like, the RMI device pointer, main character energy.
• addr — The start address to read from. Where the reading begins, periodt.
• buf — The read buffer. The memory spot where the bytes go.
• len — Length of the read buffer. Gotta know how much room we’re working with, no cap.

🦋 DESCRIPTION 🦋

Okay so the tea: this reads a block of byte data using the underlying transport protocol into the memory pointed by buf. It returns 0 on success or a negative error code. Success = 0, negative error code = not the vibe. Fr fr.
