bson_uint32_to_string − bson_uint32_to_string()
size_t bson_uint32_to_string (uint32_t value, const char **strptr, char *str, size_t size);
• |
value: A uint32_t. |
|||
• |
strptr: A location for the resulting string pointer. |
|||
• |
str: A location to buffer the string. |
|||
• |
size: A size_t containing the size of str. |
Converts value to a string.
If value is from 0 to 999, it will use a constant string in the data section of the library.
If not, a string will be formatted using str and snprintf().
strptr will always be set. It will either point to str or a constant string. Use this as your key.
Each element in a BSON array has a monotonic string key like "0", "1", etc. This function is optimized for generating such string keys.
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); }
The number of bytes in the resulting string.
