COMPUTETRANSID

This procedure converts the individual numeric parts of an externally formatted

transaction identifier to internal form. All output parameters are undefined unless a

status of 0 (successful) is returned. If omitted, the tm-flags parameter defaults to 0.

Syntax for C Programmers

Note. This procedure can be called from 32-bit and 64-bit applications.

STRUCT Type_Flags_Struct (*) FIELDALIGN (SHARED2);

BEGIN

Fixed Flags[0:-1];

UNSIGNED(8) User_Info;

These bits may be set by the customer and are not the

concern of TMF.

Note: 8 bits allows 256 possibilities. These bits will

not be evaluated by TMF, they will simply be carried

with the transaction.

BIT_FILLER 53;

Reserved bits for HP internal use. Should be

initialized to zero.

UNSIGNED(1) No_Capacity_Abort;

If set to true, the transaction is not subject to TMF

45% of audit-trail use limit.

BIT_FILLER 2;

Reserved bits for HP internal use. Should be initialized

to zero.

END;

Note. EPTAL callers can pass 64-bit pointers by specifying the compiler directives

__EXT64 and SETTOG _64BIT_CALLS before sourcing from the EXTDECS file.
