The name of the collation is a UTF-8 string for sqlite3_create_collation() and sqlite3_create_collation_v2() and a UTF-16 string in native byte order for sqlite3_create_collation16().

/* IMP: R-32806-65233 */
# EVIDENCE-OF: R-32806-65233 The fourth argument, pArg, is an

/* IMP: R-51589-21047 */
# EVIDENCE-OF: R-51589-21047 The fifth argument, xCallback, is a pointer

R-17004-26469-33978-15550-51185-63234-25288-10208 tcl slt th3 src

Multiple collating functions can be registered using the same name but with different eTextRep parameters and SQLite will use whichever function requires the least amount of data transformation.

th3/req1/createcoll01.test:226

/* IMP: R-17004-26469 */
# EVIDENCE-OF: R-17004-26469 Multiple collating functions can be

# data transformation.

R-57596-15697-28996-29191-00172-44025-23710-23803 tcl slt th3 src

If the xCallback argument is NULL then the collating function is deleted.

th3/req1/createcoll01.test:204

/* IMP: R-57596-15697 */
# EVIDENCE-OF: R-57596-15697 If the xCallback argument is NULL then the

R-63294-00538-51136-33751-00245-32067-21028-12625 tcl slt th3 src

When all collating functions having the same name are deleted, that collation is no longer usable.

th3/req1/createcoll01.test:330

/* IMP: R-63294-00538 */
# EVIDENCE-OF: R-63294-00538 When all collating functions having the

R-42196-45693-64496-49282-35220-26786-47093-56372 tcl slt th3 src

The collating function callback is invoked with a copy of the pArg application data pointer and with two strings in the encoding specified by the eTextRep argument.

th3/req1/createcoll01.test:44

/* IMP: R-42196-45693 */
# EVIDENCE-OF: R-42196-45693 The collating function callback is invoked

R-05416-57569-14245-59554-42970-16556-04782-39407 tcl slt th3 src

The sqlite3_create_collation_v2() works like sqlite3_create_collation() with the addition that the xDestroy callback is invoked on pArg when the collating function is deleted.

th3/req1/createcoll01.test:196

/* IMP: R-05416-57569 */
# EVIDENCE-OF: R-05416-57569 The sqlite3_create_collation_v2() works

R-59553-21705-43899-06784-22214-40480-29104-54159 tcl slt th3 src

Collating functions are deleted when they are overridden by later calls to the collation creation functions or when the database connection is closed using sqlite3_close().

th3/req1/createcoll01.test:200

/* IMP: R-59553-21705 */
# EVIDENCE-OF: R-59553-21705 Collating functions are deleted when they

R-16618-15294-40098-25515-23421-58217-44729-28455 tcl slt th3 src

The xDestroy callback is not called if the sqlite3_create_collation_v2() function fails.

th3/req1/createcoll01.test:320

/* IMP: R-16618-15294 */
# EVIDENCE-OF: R-16618-15294 The xDestroy callback is not called if the
