BSON_UINT32_TO_STRING(3)

💅 BSON_UINT32_TO_STRING 💅

okay bestie, real talk: this is bson_uint32_to_string from libbson — the little function that turns a uint32_t into a string, and it's lowkey iconic at it. Let's get into it 🫶

✨ SYNOPSIS ✨

size_t
bson_uint32_to_string (uint32_t value,
                       const char **strptr,
                       char *str,
                       size_t size);

that's the whole signature, no cap. four args, returns a size_t. slay.

🎀 PARAMETERS 🎀

• value — a uint32_t. that's the number you wanna stringify, periodt.
• strptr — a location for the resulting string pointer. like, a const char ** where the answer gets dropped.
• str — a location to buffer the string. your scratch space, bestie.
• size — a size_t containing the size of str. gotta tell it how much room it's working with 🌸

🦋 DESCRIPTION 🦋

so it converts value to a string. that's the vibe.

if value is from 0 to 999, it will use a constant string in the data section of the library. no formatting, no snprintf(), just a pre-baked constant sitting there looking cute. ✨

if not — like, if your number is outside that 0 to 999 range — a string will be formatted using str and snprintf(). so now it's writing into your buffer, okay?

and here's the important bit, so listen up 👑: strptr will always be set. it will either point to str or a constant string. use this as your key. always. no exceptions. iykyk.

🌈 ARRAY ELEMENT KEY BUILDING 🌈

each element in a BSON array has a monotonic string key like "0", "1", etc. and this function? this function is optimized for generating such string keys. it's giving purpose-built. it's giving main character energy. 🔥

char str[16];
const char *key;
uint32_t i;

for (i = 0; i < 10; i++) {
   bson_uint32_to_string (i, &key, str, sizeof str);
   printf ("Key: %s\n", key);
}

look at that loop go 😭 sizeof str is 16, the keys come out 0 through 9, and printf does its thing. chef's kiss.

---

⭐ RETURNS ⭐

the number of bytes in the resulting string. that's it, that's the return value 💜
