Hi SDL expert.
I'm using Telelogic Tau SDL 4.4.
I try to pass in argument to a C function the address memory of a buffer
declared in SDL. But, I have a problem with TYPE in SDL that I don't know
how to solve.
* A .PR file is generated by CPP2SDL with the following signature of the
NEWTYPE global_namespace /*##NOTYPE*/
GetDataNext : int, ptr_unsigned_char -> int;
ENDNEWTYPE global_namespace;EXTERNAL 'C';
NEWTYPE ptr_unsigned_char Ref( unsigned_char);
ptr_unsigned_char : ->
ptr_unsigned_char;/* implicit parameter-less constructor */
ptr_unsigned_char : ptr_unsigned_char ->
ptr_unsigned_char;/* implicit copy constructor */
ENDNEWTYPE ptr_unsigned_char;EXTERNAL 'C';
* I define in SDL, the following types:
SYNTYPE SizeDataBuff = Integer
NEWTYPE DataBuffType Array(SizeDataBuff,Octet)
* I try many things but the following operations seems to me correct:
DCL dataBuff DataBuffType;
DCL ptBuff ptr_unsigned_char;
task ptBuff := &<<TYPE Octet>>dataBuff;
task nDataLen := GetDataNext( 217, ptBuff );
* I got this error:
1: ERROR 372 No visible variable, formal parameter, synonym, literal or
operator with this name
ptBuff := & <<type Octet>> ? dataBuff
Do you have an idea or suggestions which could help me to solve my problem?
