Syntax Format - spatial_geostan - 2024.00

The format for the syntax of each function is:

ReturnType FunctionName (ArgumentType identifier, ArgumentType identifier )

where:

• ReturnType is the type of Return value associated with the function.
• FunctionName is the name of the function.
• ArgumentType is the type of the identifier that follows.
• identifier is the descriptive name of the argument.

All examples in the function reference using C.

Return Value Explanations

The following table lists the library function return values and their explanations.

Using the Spatial+ Library in Windows

When using Spatial+ on Windows, be sure to define the _WINDOWS symbol. Your project must define one or both of the following:

NT or/and _WIN32

You are not warned with compile or link errors if you fail to define these symbols; however, your application will not function properly and can result in insufficient stack space.

Microsoft compilers typically define these symbols for you, but Precisely strongly recommends that you define them in your project for completeness

When using Spatial+ in UNIX, be sure the following symbol is defined:

_unix (or) _UNIX

About the cc Compiler

Many UNIX and Linux systems have a "cc" compiler for use in system configuration. This compiler is provided because many UNIX system kernels require compilation of device drivers to make system changes. The "cc" compiler is not intended to be a robust or complete development system. Spatial+ performs best using the UNIX optimizing compiler option. Precisely recommends that UNIX developers contact their UNIX vendor and purchase the optimizing compiler option before using Spatial+.

Precisely libraries require certain standard libraries which are available on every UNIX development platform, but may not be found unless the appropriate system option has been installed.¹ For more information on compiling and linking C programs with object dependencies, see Using Spatial+ with UNIX.
