Annotation of 43BSDTahoe/ucb/tn3270/api/README, revision 1.1

1.1     ! root        1: apilib/
        !             2: 
        !             3: The files in this directory are not part of tn3270 proper.
        !             4: 
        !             5: They provide a C interface to the 3270 Applications Programming
        !             6: Interface (API) provided by tn3270.
        !             7: 
        !             8: This interface is modeled after (and supposed to be compatible
        !             9: with) the "low level" API provided with IBM's 3270 PC control
        !            10: program version 3.  Note that we only provide a subset of the
        !            11: API functionality.  This subset is (again supposed to be) consistent
        !            12: with that subset provided by the IBM PC 3270 Emulation Program
        !            13: version 3.00.  This subset is (somewhat sketchily) documented
        !            14: in Volume 4, Number 4 of the IBM Personal Computer Proceedings.
        !            15: The 3270 PC API itself is documented in SA23-0221 (I have revision
        !            16: -01) "IBM 3270 Personal Computer Control Program -- Programming
        !            17: Guide".
        !            18: 
        !            19: The INTENT is to allow the API from both MSDOS and from Unix.  Note,
        !            20: however, that at the current time only MSDOS is supported.
        !            21: 
        !            22: Now, to program:
        !            23: 
        !            24: First, call "api_init()".  If it returns "1", then all is OK.  If
        !            25: it returns "0", then the API is not active.
        !            26: 
        !            27: From then on, call whatever seems right.
        !            28: 
        !            29: You will need to include "../ctlr/oia.h" and "../api/api.h", at a
        !            30: minimum.
