Functions are divided into families consisting of routines related in their duties.

• All Glide functions are prefixed with gr;
• all Glide Utility functions use gu as the prefix.
• Glide uses the mixed caps convention for function names.
• When function names appear in the text of this manual, they will be shown in bold face type.
• Actual function names end with ‘()’; function family names DO NOT.
• The Glide prefix is immediately followed by the family name, for example grDrawTriangle() and grDrawPolygon() are both parts of the grDraw family.


The internal name for the Voodoo Graphics subsystem is “SST-1”or “SST”.
Some function names, type definitions, and constants within Glide reflect this internal name, which is easier to type than Voodoo Graphics.
For example, grSstOpen() initializes the hardware.

Constants are named values that are defined in glide.h. The names of constants use all uppercase letters, as in MAX_NUM_SST and GR_TEXTUREFILTER_BILINEAR and will be shown in Courier font when they appear in the text of this manual.
 

• C specifications for functions and data types will be displayed in shaded rectangles throughout this manual.
• Glide type definitions are shown in Helvetica type to distinguish them from the C keywords and primitive types.
• Glide makes use of enumerated types for function arguments in order to restrict them to the defined set of values. Enumerated types end with _t, as in GrColorFormat_t.
• Glide variable names and function arguments will be italicized in both the C specifications and the text.
• Code segments use Courier font.
