π gpiod_set_raw_array_value_cansleep β¨
okay so welcome to the Kernel API Manual, bestie π«Ά β this page is about the little function whose name got chopped in the header (you know, the gpiod_set_ra...lue_cansleep(9) thing π), and yes it's the whole long one: gpiod_set_raw_array_value_cansleep. buckle up, she's a mouthful but she's iconic π
πΈ NAME πΈ
gpiod_set_raw_array_value_cansleep β assign values to an array of GPIOs π
β¨ SYNOPSIS β¨
int gpiod_set_raw_array_value_cansleep (unsigned int array_size , struct
gpio_desc **desc_array , struct gpio_array *array_info , unsigned long
*value_bitmap );
π¦ ARGUMENTS π¦
array_sizeβ how many elements live in the descriptor array / value bitmap, fr fr. that's the count, no more no less πdesc_arrayβ the array of GPIO descriptors whose values are gonna get assigned π«array_infoβ info about whether the fast bitmap processing path applies here πvalue_bitmapβ the bitmap of values you're assigning, periodt β¨
π DESCRIPTION π
so what she does: she sets the raw values of the GPIOs. and "raw" means the values of the physical lines β without regard for their ACTIVE_LOW status π like, she does not care about that, not even a little.
this function is to be called from contexts that can sleep π΄ β that's literally the whole vibe, don't call her from somewhere that can't nap, okay?
β RETURN β
0 on success, or negative errno on failure π β classic.

ngl bestie, that's the whole page β every flag, every path, every sibling function, all accounted for π no cap.
okay byeee, this one came from ./drivers/gpio, dated October 2026, and yes it's still filed under that cursed truncated name gpiod_set_ra...lue_cansleep(9) π mwah π
