EXTRN CODE ( FUNCTION ) gives L16 if FUNCTION is BIT

Douglas Hewett

uvision 2 v2.40, c51 v7.09, bl51 v5.03 gives:

*** WARNING L16: UNCALLED SEGMENT, IGNORED FOR OVERLAY PROCESS
SEGMENT: ?PR?IS_OK_INC_DTARGET_SPD?SPDLIM

spdlim.c has
bit IS_OK_INC_DTARGET_SPD( void )
which returns a bit.

(1) how do I fix this?

    The lst gives:

    IS_OK_INC_DTARGET_SPD. PUBLIC CODE PROC 0000H -----

    and the link map shows

    CODE 35A8H 0096H INBLOCK ?PR?IS_OK_INC_DTARGET_SPD?SPDLIM

    for the PRogram part and

    BIT 0020H.3 0000H.1 UNIT ?BI?IS_OK_INC_DTARGET_SPD?SPDLIM

    which, I assume, is for the return value.

    By the way, I read the C manual (Bit Types, p. 98 and Func. Return Values, p. 120) before my original post. I did not see any special note or warning for interfacing C to assy where the return value from a C function is BIT.

    Am I missing something?
