Obsolete STREAMS parameters

NQUEUE

Formerly, the number of STREAMS queues to be configured. Queues are dynamically allocated.

NUMSP

This parameter had no function in Release 4; it was kept for compatibility with Release 3.2.

NSTREAM

Formerly, the number of ``Stream-head'' (stdata) structures to be configured. These structures are dynamically allocated.

NSTREVENT

Formerly, the initial number of Stream event cells to be configured. Dynamically allocated.

MAXSEPGCNT

Formerly, the number of additional pages of memory that can be dynamically allocated for event cells.

NMUXLINK

Formerly, the maximum number of multiplexor links to be configured. Dynamically allocated.

NBLK4096

Formerly, the number of STREAMS data blocks and buffers to be allocated for each size class was controlled by the parameters NBLK4 through NBLK4096. In Release 4, STREAMS data blocks and message buffers were dynamically allocated.

NBLK2048

NBLK1024

NBLK512

NBLK256

NBLK128

NBLK64

NBLK16

NBLK4

STRLOFRAC

Formerly, the percentage of data blocks of a given class at which low-priority block allocation requests are automatically failed.

STRMEDFRAC

Formerly, the percentage cutoff at which medium priority block allocations are failed.

NUMTIM

Formerly, the maximum number of STREAMS modules that can be pushed by the Transport Library Interface (TLI). This value controls the number of data structures used to hold pushed streams modules configuration data.

NUMTRW

Formerly, the number of Transport Library Interface (TLI) read/write data structures to allocate in kernel data space.
