As far as I can see they are not documented on their own.

They are the core of a base64 BIO created by BIO_f_base64(), 
which does have a (brief) manpage, but they are exposed in 
bio/bio.h so it's not clear if they 'should' be used alone.

They do basic mem-to-mem base64 encode and decode respectively.
The source is in crypto/evp/encode.c and is simple enough to read.
Or b64 encode/decode is simple enough to juse write your own.
