NAME

       pmemblk_set_zero()(DEPRECATED),   pmemblk_set_error()(DEPRECATED)   -   block   management
       functions

SYNOPSIS

              #include <libpmemblk.h>

              int pmemblk_set_zero(PMEMblkpool *pbp, long long blockno);
              int pmemblk_set_error(PMEMblkpool *pbp, long long blockno);

DESCRIPTION

       The pmemblk_set_zero() function writes zeros to block number blockno in persistent  memory
       resident array of blocks pbp.  Using this function is faster than actually writing a block
       of zeros since libpmemblk(7) uses metadata to indicate the block should read back as zero.

       The pmemblk_set_error() function  sets  the  error  state  for  block  number  blockno  in
       persistent  memory resident array of blocks pbp.  A block in the error state returns errno
       EIO when read.  Writing the block clears the error state and returns the block  to  normal
       use.

RETURN VALUE

       On success, pmemblk_set_zero() and pmemblk_set_error() return 0.  On error, they return -1
       and set errno appropriately.
