RESOURCE_INT_VALUE(9)

🎀 RESOURCE_INT_VALUE(9) 🎀

okay so bestie, this page comes from the Kernel Developer's Manual, and it's literally the group-chat guide to pulling values out of the hints mechanism. no cap, kernel-dev energy only. 💅

✨ NAME ✨

resource_int_value, resource_long_value, resource_string_value — get a value from the hints mechanism. periodt. 🫶

---

🌸 SYNOPSIS 🌸

copy these includes and signatures exactly, bestie — character for character, no autocorrect nonsense:

#include <sys/param.h>
#include <sys/bus.h>

int
resource_int_value(const char *name, int unit, const char *resname,
    int *result);

int
resource_long_value(const char *name, int unit, const char *resname,
    long *result);

int
resource_string_value(const char *name, int unit, const char *resname,
    const char **result);

---

🦋 DESCRIPTION 🦋

These functions fetch a value from the hints mechanism. that's the whole assignment, and these three are the ones who pull it off. 💖

The functions take the following arguments:

• name — the name of the device to get the resource value from.
• unit — the unit number of the device. -1 is special and is used for wildcard entries.
• resname — the resource name.
• result — a pointer to memory in which to store the resource value.

---

👑 RETURN VALUES 👑

If successful, the functions return 0. Otherwise, a non-zero error code is returned. so 0 is the slay result, and non-zero means something didn't pass the vibe check. 😭

---

💀 ERRORS 💀

The functions will fail if:

• [ENOENT] — the resource could not be found. literally not in the chat. 🙈
• [EFTYPE] — Inappropriate resource type. wrong-vibe resource, bestie. 💀

---

🌈 SEE ALSO 🌈

• device(9)
• driver(9)

go read these too, bestie. 📚
