It removes functions which depend on the "stdio" functions (defined in stdio.h, which perform I/O using the FILE * type). I assume this is useful when openssl is being compiled for use in an embedded environment or other special situation where stdio is not available. I think it's not a macro that users of openssl are expected to define; instead, it's defined when openssl is configured, and users of the library can check whether it's defined in openssl's headers (probably via opensslconf.h). ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
