aa_perm_mask_to_str(9)

🌸 NAME 🌸

aa_perm_mask_to_str — convert a perm mask to its short string

okay so bestie, welcome to the aa_perm_mask_to_str(9) page from the Kernel API Manual ✨ this one is literally about converting a perm mask to its short string, and it's giving very specific-buffer-energy 💅

✨ SYNOPSIS ✨

void aa_perm_mask_to_str (char *str , size_t str_size , const char *chrs , u32 mask );

No cap, that's the whole signature: it returns void, takes four args, and we're about to go through each one like a group-chat roll call 🫶

🫶 ARGUMENTS 🫶

• str — character buffer to store string in (at least 10 characters). Bestie, the page literally says at least 10 characters, so don't skimp on that buffer 😭
• str_size — size of the str buffer, periodt.
• chrs — NUL-terminated character buffer of permission characters. It's the character source, iykyk.
• mask — permission mask to convert. This is the mask getting the short-string treatment ✨
