font_data_is_equal(9)

okay so bestie, this is font_data_is_equal(9) from the Kernel API Manual ✨ — the little equality-checker for font data, and we're gonna get into it 💅.

🎀 NAME 🎀

font_data_is_equal — compares font data for equality 🫶

💖 SYNOPSIS 💖

bool font_data_is_equal (font_data_t *lhs , font_data_t *rhs );

🌸 ARGUMENTS 🌸

• lhs — left-hand side font data, main character on the left 💖
• rhs — right-hand-size font data (their spelling, not mine 😭)

✨ DESCRIPTION ✨

Font data is equal if it contains the same sequence of values. The helper also uses the checksum, if both arguments contain it 👑

Font data coming from different origins — internal or from user space — is never equal. Allowing that would break reference counting, so this is a hard no, no cap 🚨

🔥 RETURN 🔥

True if the given font data is equal, false otherwise. Simple as that, bestie ✅
