I'm not too familiar with the code. It's looks pretty good altogether. Here's
just a few little things I noticed:

should be `return (NULL);'
| +
| + sroom = roundup(sizeof(struct cjprivate), 8);
| + sroom2 = sroom + strlen(cfname) + 1;
| + sroom2 = roundup(sroom2, 8);
| + msize = sroom2 + CTI_LINEMAX;
| + msize = roundup(msize, 8);
| + cpriv = (struct cjprivate *)malloc(msize);
| + if (cpriv == NULL)
| + return NULL;
| + memset(cpriv, 0, msize);
| +
| + cpriv->pub.cji_fname = (char *)(cpriv + sroom);
| + strcpy(cpriv->pub.cji_fname, cfname);
| + cpriv->cji_buff = (char *)(cpriv + sroom2);
| + cpriv->cji_eobuff = (char *)(cpriv + msize - 1);
| +
| + cpriv->cji_fstream = cfile;
| +
| + /*

strcmp() returns 0 for match

This should line up.
