i2c_acpi_get_i2c_resource(9)

💅 i2c_acpi_get_i2c_resource — so you wanna grab an I2cSerialBus resource? bestie, same

okay so real quick — this is a page from the Kernel API Manual (section 9, the kernel-API girlies know 👑), and it's all about i2c_acpi_get_i2c_resource, aka "gets I2cSerialBus resource if type matches". that's the whole NAME situation, no notes 💖

---

✨ SYNOPSIS ✨

bool i2c_acpi_get_i2c_resource (struct acpi_resource *ares , struct
       acpi_resource_i2c_serialbus **i2c );

not me obsessing over a function that returns a bool — she's giving "yes or no, no maybes" energy and honestly? iconic 🎀

---

🌸 ARGUMENTS 🌸

• ares — the ACPI resource. that's the thing you're handing over for inspection, bestie 🦋
• i2c — a pointer to the I2cSerialBus resource, and this is where that pointer gets returned to you. like, you bring the bucket, the function fills the bucket 🪣✨

---

💜 DESCRIPTION 💜

so here's the vibe check 🔥 this function checks if the given ACPI resource (ares) is of type I2cSerialBus. and if it is? slay. it returns a pointer to it right back to the caller.

and the return value, since you're gonna ask: it returns true if the resource type is of I2cSerialBus, otherwise false. simple as that, no cap 💯

ngl this is the "are you the one or not" of kernel functions and she answers immediately 🙈
