BSON_UINT32_TO_STRING(3) libbson BSON_UINT32_TO_STRING(3) SYNOPSIS size_t bson_uint32_to_string (uint32_t value, const char **strptr, char *str, size_t size); PARAMETERS * 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. DESCRIPTION Converts value to a string. If value is from 0 to 999, it will use a constant string in the data sec- tion 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. ARRAY ELEMENT KEY BUILDING 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); } RETURNS The number of bytes in the resulting string.
