ats - What is the meaning of ATS_EXTERN_PREFIX? -

-

for instance, saw following line in atslib:

#define ats_extern_prefix "atslib_"

what meaning of ats_extern_prefix? purpose?

if have #define ats_extern_prefix "foo_" , extern fun bar (...): ... = "mac#%", external name of bar becomes ${ats_extern_prefix}bar, i.e. foo_bar.

essentially, '%' in declaration being replaced value of ats_extern_prefix.
