The format for the syntax of each function is:
ReturnType FunctionName(ArgumentType identifier, ArgumentType
identifier)
where:
ReturnTypeis the type of return value associated with the function.-
FunctionNameis the name of the function. ArgumentTypeis the type of the identifier that follows.-
identifieris the descriptive name of the argument.
Primitive data types used are as follows:
| intl | signed integer |
| double | 64-bit floating point |
| pstr | pointer to null-terminated string |
| gdlHandle | 64-bit1 signed integer |
| gdlFileHandle | 64-bit1 signed integer |
| gdlShape | 64-bit1 signed integer |
| GsId | 64-bit1 signed integer |
1The size of the pointer is dependent on the operating system: 64-bit for a 64-bit OS. |
All examples in the function reference are shown using "C."
Note: The return values and input values provided for each function are explained in detail in
"Summary of Return and Input
Values."
