- * @function:
- * FT_Load_Sfnt_Table
- *
- * @description:
- * Load any font table into client memory.
- *
- * @input:
- * face ::
- * A handle to the source face.
- *
- * tag ::
- * The four-byte tag of the table to load. Use the value~0 if you want
- * to access the whole font file. Otherwise, you can use one of the
- * definitions found in the @FT_TRUETYPE_TAGS_H file, or forge a new
- * one with @FT_MAKE_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 ... }
- *
- * buffer = malloc( length );
- * 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).
