NAME

       pmem2_config_new(),  pmem2_config_delete()  -  allocate and free a configuration structure for a libpmem2
       mapping

SYNOPSIS

              #include <libpmem2.h>

              struct pmem2_config;
              int pmem2_config_new(struct pmem2_config **cfg);
              int pmem2_config_delete(struct pmem2_config **cfg);

DESCRIPTION

       The pmem2_config_new() function instantiates a new (opaque) configuration structure, pmem2_config,  which
       is  used  to define mapping parameters for a pmem2_map_new() function, and returns it through the pointer
       in *cfg.

       New configuration is always initialized with default values for  most  parameters,  which  are  specified
       alongside  the  corresponding setter function.  The application must explicitly set the granularity value
       for the mapping.

       The pmem2_config_delete() function frees *cfg returned by pmem2_config_new() and sets *cfg to  NULL.   If
       *cfg is NULL, no operation is performed.

RETURN VALUE

       The  pmem2_config_new()  function  returns  0 on success or a negative error code on failure.  pmem2_con‐
       fig_new() does set *cfg to NULL on failure.

       The pmem2_config_delete() function always returns 0.

ERRORS

       pmem2_config_new() can fail with the following error: - -ENOMEM - out of memory
