ZCOM C I/F Library Routines

 

 

ZINFO (3X)

PARAMETERS

 

 

zap

ZCOM address pointer. The node field is used to indicate from which node

 

to retrieve the information. The uses of zlu and zcs depend on the specified

 

mode.

 

mode

Type of information to return:

 

ZcZLU_TBL

(0) - ZLU Descriptor information

 

ZcLTT_TBL

(1) - Logical Terminal Table information

 

ZcPTT_TBL

(2) - Physical Terminal Table information

 

ZcHDR_TBL

(3) - Header information (zlu and zcs are not used)

 

ZcIFT_TBL

(4) - Interface Table (zlu is the interface number, zcs

 

 

is not used)

 

ZcNODE_BYNU

(5) - Node entry (zlu is the required node number, zcs

 

M

is not used)

 

ZcNODE_BYIDX

(6) - Node entry (zlu is the index within the node

 

 

table, ranging

 

 

from 0 to maximum-1, zcs is not used)

 

Bit 15 - When this bit (ZCOM_ZINFO_NAVL) is set, zinfo will return the

 

configured ZLU, Logical and Physical terminal information for

 

non-available terminals. A non-available terminal ZLU would normally

 

result in a “Terminal is not available” error (ZENAVL[-74]). This bit has

 

no effect for modes ZcHDR_TBL, ZcIFT_TBL, ZcNODE_BYNUM or

 

ZcNODE_BYIDX.

 

ibuf

Buffer for return data. The full description of the layout of the return

(Return

buffer is contained in the Chapter 3, Tables and Data Structures section.

Param)

 

 

len

Maximum number of bytes to be returned in ibuf. If the specified length is

 

smaller than the requested table size, a truncated section of the table is

 

returned. If the specified length is larger, only the size of the requested

 

table is returned.
