Detailed Description

Various utility functions for internal use.

These functions are shared code and may be used by any part of GLFW Each platform may add its own utility functions, but those may only be called by the platform-specific code

Function Documentation

void _glfwAllocGammaArrays ( GLFWgammaramp ramp,
unsigned int  size 
)

Definition at line 189 of file monitor.c.

_GLFWmonitor* _glfwAllocMonitor ( const char *  name,
int  widthMM,
int  heightMM 
)

Allocates and returns a monitor object with the specified name and dimensions.

Parameters
[in]nameThe name of the monitor.
[in]widthMMThe width, in mm, of the monitor's display area.
[in]heightMMThe height, in mm, of the monitor's display area.
Returns
The newly created object.

Definition at line 166 of file monitor.c.

const _GLFWfbconfig* _glfwChooseFBConfig ( const _GLFWfbconfig desired,
const _GLFWfbconfig alternatives,
unsigned int  count 
)

Chooses the framebuffer config that best matches the desired one.

Parameters
[in]desiredThe desired framebuffer config.
[in]alternativesThe framebuffer configs supported by the system.
[in]countThe number of entries in the alternatives array.
Returns
The framebuffer config most closely matching the desired one, or NULL if none fulfilled the hard constraints of the desired values.

Definition at line 191 of file context.c.

const GLFWvidmode* _glfwChooseVideoMode ( _GLFWmonitor monitor,
const GLFWvidmode desired 
)

Definition at line 216 of file monitor.c.

int _glfwCompareVideoModes ( const GLFWvidmode first,
const GLFWvidmode second 
)

Performs lexical comparison between two GLFWvidmode structures.

Definition at line 266 of file monitor.c.

void _glfwFreeGammaArrays ( GLFWgammaramp ramp)

Definition at line 197 of file monitor.c.

void _glfwFreeMonitor ( _GLFWmonitor monitor)

Frees a monitor object and any data associated with it.

Definition at line 176 of file monitor.c.

void _glfwFreeMonitors ( _GLFWmonitor **  monitors,
int  count 
)

Definition at line 206 of file monitor.c.

GLboolean _glfwIsValidContext ( const _GLFWctxconfig ctxconfig)

Checks whether the current context fulfils the specified hard constraints.

Parameters
[in]ctxconfigThe desired context attributes.
Returns
GL_TRUE if the context fulfils the hard constraints, or GL_FALSE otherwise.

Definition at line 478 of file context.c.

GLboolean _glfwIsValidContextConfig ( const _GLFWctxconfig ctxconfig)

Checks whether the desired context attributes are valid.

Parameters
[in]ctxconfigThe context attributes to check.
Returns
GL_TRUE if the context attributes are valid, or GL_FALSE otherwise.

This function checks things like whether the specified client API version exists and whether all relevant options have supported and non-conflicting values.

Definition at line 90 of file context.c.

GLboolean _glfwRefreshContextAttribs ( const _GLFWctxconfig ctxconfig)

Retrieves the attributes of the current context.

Parameters
[in]ctxconfigThe desired context attributes.
Returns
GL_TRUE if successful, or GL_FALSE if the context is unusable.

Definition at line 354 of file context.c.

void _glfwSplitBPP ( int  bpp,
int red,
int green,
int blue 
)

Splits a color depth into red, green and blue bit depths.

Definition at line 271 of file monitor.c.

int _glfwStringInExtensionString ( const char *  string,
const char *  extensions 
)

Searches an extension string for the specified extension.

Parameters
[in]stringThe extension string to search.
[in]extensionsThe extension to search for.
Returns
GL_TRUE if the extension was found, or GL_FALSE otherwise.

Definition at line 500 of file context.c.
