pblock

The parameter block is the hash table that holds pb_entry structures. Its contents are transparent to most code. This data structure is frequently used in NSAPI. It provides the basic mechanism for packaging up parameters and values. There are many functions for creating and managing parameter blocks, and for extracting, adding, and deleting entries. See the functions whose names start with pblock_ in Chapter 7, NSAPI Function Reference. You should not write code that accesses pblock data fields directly.

typedef struct {
    int hsize;
    struct pb_entry **ht;
} pblock;
