- *

- * tag ::

- *

- * offset ::

- * The starting offset in the table (or file if tag == 0).

- *

- * @output:

- * buffer ::

- * The target buffer address. The client must ensure that the memory

- * array is big enough to hold the data.

- *

- * @inout:

- * length ::

- * If the `length' parameter is NULL, then try to load the whole table.

- * Return an error code if it fails.

- *

- * Else, if `*length' is~0, exit immediately while returning the

- * table's (or file) full size in it.

- *

- * Else the number of bytes to read from the table or file, from the

- * starting offset.

- *

- * @return:

- * FreeType error code. 0~means success.

- *

- * @note:

- * If you need to determine the table's length you should first call this

- * function with `*length' set to~0, as in the following example:

- *

- * {

- * FT_ULong length = 0;

- *

- * error = FT_Load_Sfnt_Table( face, tag, 0, NULL, &length );

- * if ( error ) { ... table does not exist ... }

- * if ( buffer == NULL ) { ... not enough memory ... }

- *

- * error = FT_Load_Sfnt_Table( face, tag, 0, buffer, &length );

- * if ( error ) { ... could not load table ... }

- * }

- *

- * Note that structures like @TT_Header or @TT_OS2 can't be used with

- * this function; they are limited to @FT_Get_Sfnt_Table. Reason is that

- * those structures depend on the processor architecture, with varying

- * size (e.g. 32bit vs. 64bit) or order (big endian vs. little endian).
