tomoyo_numscan(9)

💖 NAME 💖

okay so bestie, meet tomoyo_numscan(9) from the Kernel API Manual. it's basically sscanf() but it stores the length of a decimal integer value. iconic behavior, honestly. ✨

✨ SYNOPSIS ✨

bool tomoyo_numscan (const char *str , const char *head , int *width ,
       const char tail );

🎀 ARGUMENTS 🎀

• str — the string to scan. literally the string we're looking at. 💅
• head — the leading string that must start with. (the prefix str has to match, bestie. 🫶)
• width — pointer to an int for storing the length of a decimal integer value after head. 🍓
• tail — optional character that must match after a decimal integer value. 🎀

🌸 DESCRIPTION 🌸

tomoyo_numscan() returns whether str starts with head and a decimal value follows head. that's the whole vibe check. it hands back a bool, and the width pointer is where the length of that decimal integer value gets stored. no cap. 💖
