C Common Runtime Library Functions

The C run-time common library contains common C functions used by the low-level encode/decode functions. These functions are identified by their rtx prefixes.

The categories of functions provided are as follows:

• Context management functions handle the allocation, initialization, and destruction of context variables (variables of type OSCTXT) that handle the working data used during the encoding or decoding of a message.
• Memory allocation macros and functions provide an optimized memory management interface.
• Doubly linked list (DList) functions are used to manipulate linked list structures that are used to model repeating XSD types and elements.
• UTF-8 and Unicode character string functions provide support for conversions to and from these formats in C or C++.
• Date/time conversion functions provide utilities for converting system and structured numeric date/time values to XML schema standard string format.
• Pattern matching function compare strings against patterns specified using regular expressions (regexp's).
• Diagnostic trace functions allow the output of trace messages to standard output.
• Error formatting and print functions allow information about encode/decode errors to be added to a context block structure and printed out.
• Memory buffer management functions handle the allocation, expansion, and de-allocation of dynamic memory buffers used by some encode/decode functions.
• Formatted print functions allow binary data to be formatted and printed to standard output and other output devices.
• Big Integer helper functions are arbitrary-precision integer manipulating functions used to maintain big integers.
