okay so this is a page from the Kernel API Manual and honestly bestie it's a short one but it's important, so let's get into it 🫢


✨ NAME ✨

ecryptfs_read_lower β€”

yeah so the original literally just leaves the description blank after the dash 😭 no cap, there is nothing there. The name is the whole thing. Moving on πŸŽ€


🌸 SYNOPSIS 🌸

int ecryptfs_read_lower (char *data , loff_t offset , size_t size ,
       struct inode *ecryptfs_inode );

like, that's the whole signature, she's a little long but she's iconic ✨


πŸ¦‹ ARGUMENTS πŸ¦‹

  • data β€” the read data gets stored here by this function. it's the destination, the little home where the bytes go 🏠
  • offset β€” byte offset in the lower file from which to read the data. like where you start scooping πŸ₯„
  • size β€” number of bytes to read from offset of the lower file and store into data. how much you're scooping πŸ’«
  • ecryptfs_inode β€” the eCryptfs inode. that's her πŸ‘‘

πŸ’œ DESCRIPTION πŸ’œ

Read size bytes of data at byte offset offset from the lower inode into memory location data. literally that's it, that's the vibe 🧚

Returns bytes read on success; 0 on EOF; less than zero on error πŸ’€ so like, check your return value bestie, i'm begging πŸ™ˆ
