This chapter provides C language definitions of Cisco IOS for S/390 data structures for use with the basic C library. It includes these sections:
Data structures that are provided by the application program as arguments of the API transport service functions are defined in this chapter and Chapter 4, Socket Library Include Files. This chapter defines these data structures as used by application programs written in C language using the basic C library.
There is a one-to-one correspondence between the API assembler language dsects and C language structures. This table shows the correspondence between dsect names and structure names:
| API Data Structure | DSECT Name | Structure Name |
|---|---|---|
| Application Program Control Block | APCB | apcb |
| APCB Exit List | APCBXL | apcbxl |
| Transport Endpoint Error Message | TEM | tem |
| Transport Service Information Block | TIB | tib |
| Transport Protocol Address | TPA | tpa |
| Transport Service Parameter List | TPL | tpl |
| Transport Protocol Options | TPO | tpo |
| Transport Endpoint State Word | TSW | tsw |
| Transport Endpoint User Block | TUB | tub |
| Transport Endpoint Exit List | TXL | txl |
| Transport Endpoint Exit Parameters | TXP | txp |
Data structures are listed in detail in the following sections.
The definitions and declarations in this section are written to ANSI C specifications, and can be used to compile programs with the IBM C/370 and SAS/C compilers. They are contained in the include file api.h.
Include files are installed on the local system as members of a partitioned data set. This data set should be included in the SYSLIB DD concatenation when the application program is compiled. The data set name is determined during installation unless changed by the local system programmer. The API member in this data set corresponds to the api.h include file.
Each page that pertains to a particular include file has the name of the file in the upper outside corner.
