Special Operations
The SSIDTOTEXT and TEXTTOSSID procedures perform these functions:
Special Operations
The SSPUT(TKN) and SSGET(TKN) procedures can perform special operations in
addition to their primary functions. Applications request special operations by
specifying special token codes in the procedure calls. Special token codes and the
operations they request are listed with each procedure description.
Manipulating Header Tokens
The SSPUT(TKN) and SSGET(TKN) procedures can also modify and retrieve the
values of some SPI message header tokens, as indicated in the procedure
descriptions.
Procedure Status
The procedure calls return a status code that summarizes the outcome of procedure
processing:
These codes are described in Appendix A, Errors
.
