The mi_get_money() function
The mi_get_money() function copies an mi_money (MONEY) value, converting any difference in alignment or byte order on the client computer to that of the server computer.
Syntax
mi_unsigned_char1 *mi_get_money(data_ptr, money_ptr)
mi_unsigned_char1 *data_ptr;
mi_money *money_ptr;- data_ptr
- A pointer to the buffer from which to copy the mi_money value.
- money_ptr
- A pointer to the buffer to which to copy the mi_money value.
Valid in client LIBMI application? Valid in user-defined routine? No Yes
Usage
The mi_get_money() function copies a value from the user-defined buffer that data_ptr references into the buffer that money_ptr references. Upon completion, mi_get_money() 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 money_ptr identifies, the returned address is n bytes advanced from the original buffer address in data_ptr.
The mi_get_money() function is useful in a receive support function of an opaque data type that contains an mi_money value. Use this function to receive an mi_money field of an opaque-type internal structure from a client application (which possibly has unaligned data buffers).
For more information about the use of mi_get_money() in a receive support function, see the Informix® DataBlade® API Programmer's Guide.
Return values
- An mi_unsigned_char1 pointer
- The new address in the data_ptr data buffer.
- NULL
- The function was not successful.
