Values for data_size and stack_size

[Scott]

I'm compiling Bind8.2.2.5 for Solaris(SunOS 5.7) and would like to
know what the default values for these src variable are:
ns_config.c:    op->data_size = 0UL;    /* use system default */
ns_config.c:    op->stack_size = 0UL;   /* use system default */
ns_config.c:    op->core_size = 0UL;    /* use system default */


I cannot find any info on the "system default" for these values.

The src named.conf file list:
 datasize default;
 stacksize default;
 coresize default;

Any ideas on what the default is or what is normal?

Thanks in advance!
