Group PJ_GUID
- group PJ_GUID
This module provides API to create string that is globally unique. If application doesn’t require that strong requirement, it can just use pj_create_random_string() instead.
Defines
-
PJ_GUID_MAX_LENGTH
PJ_GUID_MAX_LENGTH specifies the maximum length of GUID string, regardless of which algorithm to use.
Functions
-
unsigned pj_GUID_STRING_LENGTH(void)
Get PJ_GUID_STRING_LENGTH constant.
-
pj_str_t *pj_generate_unique_string(pj_str_t *str)
Create a globally unique string, which length is PJ_GUID_STRING_LENGTH characters. Caller is responsible for preallocating the storage used in the string.
- Parameters:
str – The string to store the result.
- Returns:
The string.
-
pj_str_t *pj_generate_unique_string_lower(pj_str_t *str)
Create a globally unique string in lowercase, which length is PJ_GUID_STRING_LENGTH characters. Caller is responsible for preallocating the storage used in the string.
- Parameters:
str – The string to store the result.
- Returns:
The string.
Variables
-
const unsigned PJ_GUID_STRING_LENGTH
PJ_GUID_STRING_LENGTH specifies length of GUID string. The value is dependent on the algorithm used internally to generate the GUID string. If real GUID generator is used, then the length will be between 32 and 36 bytes. Application should not assume which algorithm will be used by GUID generator.
Regardless of the actual length of the GUID, it will not exceed PJ_GUID_MAX_LENGTH characters.
