ctGetSequenceAttrs

Declaration

NINT ctGetSequenceAttrs(LONG seqhnd, pctSEQATTR pseqattr);

Description

Retrieves the attributes for the specified sequence. seqhnd specifies the sequence handle. pseqattr points to a ctSEQATTR structure that receives the sequence attribute values.

Return Values

Value	Symbolic Constant	Explanation
0	NO_ERROR	Successfully created the sequence.
900	SEQDUP_ERR	A sequence having the specified name already exists.
903	SEQTYP_ERR	The specified sequence type contains an invalid combination of sequence type options.
904	SEQINI_ERR	The initial value specified for the sequence is out of range.
905	SEQCUR_ERR	The current value specified for the sequence is out of range.
906	SEQLIM_ERR	The limit value specified for the sequence is out of range.
907	SEQINC_ERR	The increment value specified for the sequence is out of range.
901	SEQNAM_ERR	An invalid sequence name was specified: the name is NULL, empty, or too long.

See FairCom DB Error Codes for a complete listing of valid error values.

Example

ctSEQATTR seqattr;

NINT rc;

** Create an incrementing sequence that starts with 1, increments by 3, and

** terminates with 100.

strcpy(seqattr.seqnam, "MyFirstSequence");

seqattr.seqini = 1;

seqattr.seqinc = 3;

seqattr.seqlim = 100;

seqattr.seqtyp = ctSEQINC | ctSEQTRM | ctSEQLIM;

if ((rc = ctCreateSequence(&seqattr))) {

printf("Error: Failed to create the sequence: %d\n", rc);

} else {

printf("Successfully created the sequence.\n");
