NAME
     bioinit - initialize a buffer structure

SYNOPSIS
     #include 
     #include 



     voidbioinit(struct buf *bp);


INTERFACE LEVEL
     Solaris DI specific (Solaris DI).

PARAMETERS
     bp     Pointer to the buffer header structure.


DESCRIPTION
     The bioinit() function initializes a  buf(9S)  structure.  A
     buffer  structure contains state information which has to be
     initialized if the memory for the buffer was allocated using
     kmemalloc(9F). This is not necessary for a buffer allocated
     using getrbuf(9F)  because  getrbuf()  will  call  bioinit()
     directly.

CONTEXT
     The bioinit() function can be called from any context.

EXAMPLES
     Example 1 Using bioinit()


       struct buf *bp = kmemalloc(biosize(), KMSLEP);
       bioinit(bp);
       /* use buffer */
