NAME

       pmemcto_stats_print - write human-readable memory pool statistics

SYNOPSIS

              #include <libpmemcto.h>

              void pmemcto_stats_print(PMEMctopool *pcp, const char *opts);

DESCRIPTION

       The  pmemcto_stats_print()  function produces messages containing statistics about the given memory pool.
       The output is printed using libpmemcto(7) internal print_func function (see pmemcto_set_funcs(3)).   That
       means  the output typically appears on stderr unless the caller supplies a replacement print_func or sets
       the environment variable PMEMCTO_LOG_FILE to direct output elsewhere.  The opts string can either be NULL
       or  it  can  contain  a  list  of  options that change the stats printed.  General information that never
       changes during execution can be omitted by specifying “g” as a character within  the  opts  string.   The
       characters  “m” and “a” can be specified to omit merged arena and per arena statistics, respectively; “b”
       and “l” can be specified to omit per size class statistics for  bins  and  large  objects,  respectively.
       Unrecognized  characters are silently ignored.  Note that thread caching may prevent some statistics from
       being completely up to date.  See jemalloc(3) for more detail (the  description  of  the  available  opts
       above was taken from that man page).
