compose-octet-array

Arguments: &rest parts

This macro implements a convenient notation for representing a vector of octets in a source file. The value of the macro call is a vector of type (array * (unsigned-byte 8)) initialized to all the octets specified in the arguments with the forms:

• string: The character code of each character in the string specifies one octet in the result vector.
• A character: The character code specifies the octet.
• An integer: The number specifies the octet.
• :[: The arguments following this argument up to an occurrence of :] are converted to hexadecimal numbers that specify each octet.
• A symbol: The symbol is treated as the name of a character that specifies the octet.
• :eval: The following argument is evaluated at run time. The value must be a sequence of values allowed as arguments to compose-octet-array-fn.

Each octet value must be in the octet value range. If not an error is signaled.

If there are no occurrences of the :eval argument, the result emitted by the macro is a constant vector. If the :eval argument is used, the macro emits a call to the compose-octet-array-fn function.
