EDCS language bindings — Part 4: C
The binding of each EDCS function utilizes the following template:
EDCS C Binding Function Name
Abstract Function: EDCS Abstract Function Name
ReturnValueDataType EDCS_FunctionName (
|
[const] |
Parameter0DataType |
parameter_0_name, |
/* parameter 0 comment */ |
|
[const] |
Parameter1DataType |
parameter_1_name, |
/* parameter 1 comment */ |
. . .
|
[const] |
ParameterNDataType |
parameter_N_name, |
/* parameter N comment */ |
);
The EDCS C binding function name is formed by a sentinal
“EDCS_” followed by the name without spaces and with words capitalized. The
EDCS abstract function name is the name used in
ISO/IEC 18025.
The return value data type and parameter data types may be
found in clause 5 of this standard or may be a standard C data type (e.g.,
void). If the parameter data type is preceded by the word “const”,
the input parameter is a pointer to a structured representation type.
The parameter names are formed by using lower case words separated by underscores.
To the right of each parameter declaration is a C comment field that provides a brief description of the parameter. If the comment begins with “OUT”, the argument is used as an output parameter; the implementation returns data to the application through this argument. Arguments without “OUT” are input-only parameters.
Abstract Function: ConvertQuantityValue
EDCS_Status_Code EDCS_ConvertQuantityValue (
|
const |
EDCS_Real_Value |
*from_value, |
/* value to convert */ |
|
|
EDCS_Real_Value |
*to_value |
/* OUT converted value */ |
);
Abstract Function: Get_Highest_Codes_Used
EDCS_Status_Code EDCS_GetHighestCodesUsed (
|
|
EDCS_Dictionary_Type |
dictionary_name, |
/* dictionary */ |
|
|
EDCS_Integer |
*standard_code, |
/* OUT highest std code */ |
|
|
EDCS_Integer |
*registered_code |
/* OUT highest reg code */ |
);
