phfree(D3)

NAME
     phfree - free a pollhead structure

SYNOPSIS
     #include <sys/poll.h>
     #include <sys/ddi.h>
     void phfree(struct pollhead *php);

   Arguments
     php       Pointer to the pollhead structure to be freed.

DESCRIPTION
     phfree frees the pollhead structure specified by php.

   Return Values
     None.

USAGE
     The structure pointed to by php must have been previously allocated by a
     call to phalloc(D3).

     On systems where the phalloc function is available, DDI/DKI conforming
     drivers should only use pollhead structures which have been allocated and
     initialized using phalloc.  Use of pollhead structures which have been
     obtained by any other means is prohibited on such systems.

   Level
     Initialization, Base or Interrupt.

   Synchronization Constraints
     Does not sleep.

     Driver-defined basic locks, read/write locks, and sleep locks may be held
     across calls to this function.
