glob(3g) -- generate pathnames matching a pattern
|
|
The structure type glob_t is defined in the header <glob.h> and includes at least the following members: MemberType MemberName Description _______________________________________________________________ size_t gl_offs Slots to reserve at start of gl_pathv. char ** gl_pathv Pointer to list of matched pathnames. size_t gl_pathc Count of paths matched by pattern. The argument pattern is a pointer to a pathname pattern to be expanded. The glob function matches all... |

Tcl/global(3) -- Access global variables
|
|
This command is ignored unless a Tcl procedure is being interpreted. If so then it declares the given varname's to be global variables rather than local ones. For the duration of the current procedure (and only while executing in the current procedure), any reference to any of the varnames will refer to the global variable by the same name. |
|
|
OpenGL/glortho(3) -- multiply the current matrix with an orthographic matrix
|
|
left, right Specify the coordinates for the left and right vertical clipping planes. bottom, top Specify the coordinates for the bottom and top horizontal clipping planes. near, far Specify the distances to the nearer and farther depth clipping planes. These values are negative if the plane is to be behind the viewer. |

OpenGL/glpassthrough(3) -- place a marker in the feedback buffer
|
|
token Specifies a marker value to be placed in the feedback buffer following a GL_PASS_THROUGH_TOKEN. |

OpenGL/glpixelzoom(3) -- specify the pixel zoom factors
|
|
xfactor, yfactor Specify the x and y zoom factors for pixel write operations. |
|
OpenGL/glpointparametersgis(3) -- set point parameters
|
|
pname The symbolic name of a point parameter. One of GL_POINT_SIZE_MIN_SGIS or GL_POINT_SIZE_MAX_SGIS or GL_POINT_FADE_THRESHOLD_SIZE_SGIS. param The parameter value. |

markerp Returns a marker for a completed asynchronous command. |
|
OpenGL/glpolygonmode(3) -- select a polygon rasterization mode
|
|
