Allocate memory
If the HCL Informix® GLS function allocates memory, this memory is only allocated within the function itself and is freed before the function returns.
No Informix GLS library function allocates memory that remains after the function returns. Therefore, you must allocate any memory for data that the Informix GLS function needs or returns.
DataBlade UDRs can assume that the Informix GLS functions allocate memory with a PER_ROUTINE memory duration.
You must ensure that memory is allocated for any return value or argument that the Informix GLS function provides to the calling program.
Tip: You must also handle memory allocation for multibyte-character and wide-character
strings that the Informix GLS functions
use.
