ZINFO (3X)

PAR AMETER S
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
M
(5) - Node entry (zlu is the required node number, zcs
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
(Return
Param)
Buffer for return data. The full description of the layout of the return
buffer is contained in the Chapter 3, Tables and Data Structures section.
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.
