nvmem_cell_...iable_le_u64(9)

NAME 💖

okay so bestie, welcome to nvmem_cell_...iable_le_u64(9) from the Kernel API Manual — the function is nvmem_cell_read_variable_le_u64, and it’s literally here to read up to 64-bits of data as a little endian number. slay. ✨

SYNOPSIS 🎀

int nvmem_cell_read_variable_le_u64 (struct device *dev , const char
*cell_id , u64 *val );

ARGUMENTS 🫶

• dev — Device that requests the nvmem cell. it’s the one asking for the read, main character energy fr.
• cell_id — Name of nvmem cell to read. yep, the name is the whole vibe check here.
• val — pointer to output value. that’s where the answer lands, bestie.

RETURN 💅

0 on success or negative errno. no cap — success is 0, and anything else is a negative errno situation. 😭
