    - Using Informix® GLS in a C-language program
      - Compile and link
      - Initialize the library
        Before you can use functions in your application, these functions must be able to access the current processing locale.
      - Informix® GLS exceptions
        Many of the functions return a unique value if they encounter an error. To further identify the cause of the error, you can use the ifx_gl_lc_errno() function to obtain the value of the error number.
      - Allocate memory
        If the function allocates memory, this memory is only allocated within the function itself and is freed before the function returns.
      - Input and output streams
      - Run the program
    - Improve program performance
  - Character processing
    These topics describe the character-processing capabilities of the library.
  - Data formatting
    You must handle the format of locale-specific data in your applications.
