+; as the one returned by function.
+;   When function returns FASM_OK condition, the output_length and
+; output_data fields are filled - with pointer to generated output
+; (somewhere within the provided memory block) and the count of bytes stored
+; there.
+;   When function returns FASM_ERROR, the error_code is filled with the
+; code of specific error that happened and error_line is a pointer to the
+; LINE_HEADER structure, providing information about the line that caused
+; the error.

+; macroinstruction. First case has the highest bit of line_number set to 0,
+; while the second case has this bit set.
+;   In the first case, the file_path field contains pointer to the path of
+; source file (empty string if it's the source that was provided directly to
+; fasm_Assemble function), the line_number is the number of line within
+; that file (starting from 1) and the file_offset field contains the offset
+; within the file where the line starts.
+;   In the second case the macro_calling_line field contains the pointer to
+; LINE_HEADER structure for the line which called the macroinstruction, and
+; the macro_line field contains the pointer to LINE_HEADER structure for the
+; line within the definition of macroinstruction, which generated this one.
