Command Suffixes and Argument Data Types

Suffix	Data Type	Typical Corresponding C-Language Type	OpenGL Type Definition
b	8-bit integer	signed char	GLbyte
s	16-bit integer	short	GLshort
i	32-bit integer	int or long	GLint,GLsizei
f	32-bit floating-point	float	GLfloar,GLclampf
d	64-bit floating-point	double	GLdouble,GLclampd
ub	8-bit unsigned integer	unsigned char	GLubyte,GLboolean
us	16-bit unsigned integer	unsigned short	GLushort
ui	32-bit unsigned integer	unsigned int or unsigned long	GLuint,GLenum,GLbittfield

OpenGL defines the typedef GLvoid. This is most often used for OpenGL commands that
accept pointers to arrays of values.
