ChapterA 11.A Integrating External Routines
A

In a??Examples of Using External Callsa??, reorder prototypes to match order in the header

In a??gtmxc_types.ha??, Note about 1 MiB limit on strings

In a??Using External Callsa??, Add null address and negative length handling

In a??Using External Callsa??, added SIGSAFE keyword

In a??Pre-allocation of Output Parametersa??, specify that when an external call exceeds its specified preallocation (gtm_string_t * or gtm_char_t * output), GT.M produces an EXCEEDSPREALLOC error.

In a??Rules to Follow in Call-Insa??, specify that using gtm_malloc is mandatory to allocate returns of pointer types to prevent memory leaks.

In a??Nested Call-Insa??, tweak ZGOTO description for GTMCI behavior

In a??Building Standalone Programsa??, removed instructions for platforms that are no longer supported.

In a??Creating a Shareable Librarya??, removed examples for currently unsupported platforms.

In a??Using External Callsa??, removed Tru64 and fixed formatting

In a??gtmxc_types.ha??, removed Tru64

In a??Relevant files for Call-Insa??, removed HP-UX

In a??Access to Non-M Routinesa??, added information about the external call arguments that do not specify a value and corrected the examples.

In a??Using External Callsa??, added a note about how arguments that do not specify a value translate to default values in C.

Improved the description of the a??Pre-allocation of Output Parametersa?? section.

In a??Rules to Follow in Call-Insa??, added a recommendation to not mix GT.M device input using read() system service with bufferred input services in fgets() family.

Added a section called a??Type Limits for Call-ins and Call-outsa??.
