19.6.130 ToBuffer (Convert Data to Buffer)
Syntax
ToBuffer (Data, Result) => Buffer
Arguments
Data must be an Integer, String, or Buffer data type.
Description
Data is converted to buffer type and the result is optionally stored into Result. If Data is an integer,
it is converted into n bytes of buffer (where n is 4 if the definition block has defined integers as 32
bits or 8 if the definition block has defined integers as 64 bits as indicated by the Definition Block
table header’s Revision field), taking the least significant byte of integer as the first byte of buffer. If
Data is a buffer, no conversion is performed. If Data is a string, each ASCII string character is
copied to one buffer byte, including the string null terminator. A null (zero-length) string will be
converted to a zero-length buffer.
19.6.131 ToDecimalString (Convert Data to Decimal String)
Syntax
ToDecimalString (Data, Result) => String
Arguments
Data must be an Integer, String, or Buffer data type.
Description
Data is converted to a decimal string, and the result is optionally stored into Result. If Data is
already a string, no action is performed. If Data is a buffer, it is converted to a string of decimal
values separated by commas. (Each byte of the buffer is converted to a single decimal value.) A
zero-length buffer will be converted to a null (zero-length) string.
19.6.132 ToHexString (Convert Data to Hexadecimal String)
Syntax
ToHexString (Data, Result) => String
Arguments
Data must be an Integer, String, or Buffer data type.
Description
Data is converted to a hexadecimal string, and the result is optionally stored into Result. If Data is
already a string, no action is performed. If Data is a buffer, it is converted to a string of hexadecimal
values separated by commas. A zero-length buffer will be converted to a null (zero-length) string.
