iommu_copy_...m_user_array(9)

💖 NAME 💖

okay so this is the Kernel API Manual page for iommu_copy_struct_from_user_array, and the header/page name is iommu_copy_...m_user_array(9) — yes, the ellipsis is serving iykyk 💅. its whole job: Copy iommu driver specific user space data from an iommu_user_data_array.

✨ SYNOPSIS ✨

the signature is literally this, bestie — don't freelance it:

iommu_copy_struct_from_user_array (kdst , user_array , data_type , index , min_last );

🎀 ARGUMENTS 🎀

• kdst — pointer to an iommu driver specific user data that is defined in include/uapi/linux/iommufd.h.
• user_array — pointer to a struct iommu_user_data_array for a user space array.
• data_type — the data type of the kdst. Must match with user_array->type.
• index — index to the location in the array to copy user data from.
• min_last — the last member of the data structure kdst points in, in the initial version.

🦋 DESCRIPTION 🦋

copy a single entry from a user array. return 0 for success, otherwise -error. that's the tea ☕✨
