NAME Globus OpenSSL Module – Modules Activation Detailed Description The globus_openssl library is motivated by the desire to make OpenSSL thread safe. This is done by allocating a mutex pool and setting relevant callback functions in the module activation functions. Any program that uses OpenSSL functions with Globus must include the globus_openssl.h header. Globus OpenSSL…
