mi_unsigned_char1 *mi_get_decimal(data_ptr, dec_ptr)
   mi_unsigned_char1 *data_ptr;
   mi_decimal *dec_ptr;

data_ptr

is a pointer to the buffer from which to copy the mi_decimal value.

dec_ptr

is a pointer to the buffer to which to copy the mi_decimal value.

Valid in Client LIBMI Application?	Valid in User-Defined Routine?
No	Yes

The mi_get_decimal( ) function copies a value from the user-defined buffer that data_ptr references into the buffer that dec_ptr references. Upon completion, mi_get_decimal( ) returns the address of the next position from which data can be copied from the data_ptr buffer. The function returns the data_ptr address advanced by n bytes, ready for a subsequent copy. In other words, if n is the length of the value that dec_ptr identifies, the returned address is n bytes advanced from the original buffer address in data_ptr.

The mi_get_decimal( ) function is useful in a receive support function of an opaque data type that contains an mi_decimal value. Use this function to receive an mi_decimal field of an opaque-type internal structure from a client application (which possibly has unaligned data buffers).

An mi_unsigned_char1 pointer

is the new address in the data_ptr data buffer.

NULL

indicates that the function was not successful.
