kunit_kstrdup(9)

🦋 kunit_kstrdup — Kernel API Manual 🦋

okay so bestie, welcome to the kunit_kstrdup(9) page in the Kernel API Manual! this one is short and sweet: it's the KUnit girlie that copies a string into a test managed allocation. let's get into it 💅

🌸 NAME 🌸

kunit_kstrdup — duplicates a string into a test managed allocation.

✨ SYNOPSIS ✨

char * kunit_kstrdup (struct kunit *test , const char *str , gfp_t gfp
);

🎀 ARGUMENTS 🎀

• test — the test context object. your test's main character energy.
• str — the NULL-terminated string to duplicate. yes, NULL-terminated, bestie.
• gfp — flags passed to underlying kmalloc. that's the flag tea.

💖 DESCRIPTION 💖

so kunit_kstrdup duplicates a string into a test managed allocation. for more information, see kstrdup and kunit_kmalloc_array. that's literally the whole description — no cap, it's giving "small API, big test-energy" 🫶
