In the meantime, a search separate from the openssl online documentation 
for the above C API's, made me find:


where I found:


which seems to be what I want.

In order to make that page "findable" from the manual pages for the C 
API's DSA_generate_parameters(), DSA_generate_key() and DSA_print_fp(), 
I'd suggest to include a link in the respective "SEE ALSO" sections.
