Name

eglQueryString — + return a string describing properties of the EGL client or of an + EGL display connection +

C Specification

+ + + + + + + + + +

+ `char const * eglQueryString(` +	EGLDisplay `display`,
	EGLint `name)`;

Parameters

+ + + display + + +: +
+ Specifies the EGL display connection. +
+
+ + + name + + +: +
+ Specifies a symbolic constant, one of + EGL_CLIENT_APIS, + EGL_VENDOR, + EGL_VERSION, or + EGL_EXTENSIONS. +
+

Description

+ eglQueryString returns a pointer to a + static, zero-terminated string describing properties of the EGL + client or of an EGL display connection. + name may be one of the following: +

+ + EGL_CLIENT_APIS + +

+ Returns a string describing which client rendering + APIs are supported. The string contains a + space-separated list of API names. The list must + include at least one of OpenGL, + OpenGL_ES, or OpenVG. + These strings correspond respectively to values + EGL_OPENGL_API, + EGL_OPENGL_ES_API, and + EGL_OPENVG_API of the + eglBindAPI, + api argument. +

+ + EGL_VENDOR + +

+ Returns the name of the vendor responsible for this EGL + implementation. The format and contents of the string + are implementation-dependent. +

+ + EGL_VERSION + +

+ Returns a version or release number. The + EGL_VERSION string is laid out + as follows: +

+ major_version.minor_version + space + vendor_specific_info +

+ Both the major and minor portions of the version + number are numeric. Their values must match the + major and + minor values returned by + eglInitialize. +

+ The vendor-specific information is optional; if + present, its format and contents are + implementation-specific. +

+ + EGL_EXTENSIONS + +

+ Returns a space separated list of supported + extensions to EGL. If there are no extensions, then + the empty string is returned. +

+ If display is + EGL_NO_DISPLAY, then the + EGL_EXTENSIONS string describes + the set of supported client + extensions. If + display is a valid, + initialized display, then the + EGL_EXTENSIONS string describes + the set of display extensions + supported by that display. The set of supported + client extensions is disjoint from the set of + extensions supported by any given display. +

Notes

+ EGL_CLIENT_APIS is supported only if + the EGL version is 1.2 or greater. +

+ A display of + EGL_NO_DISPLAY is supported only if the EGL + version is 1.5 or greater. +

Errors

+ NULL is returned on failure. +

+ EGL_BAD_DISPLAY is generated if + display is not an EGL display connection, + unless display is + EGL_NO_DISPLAY and + name is + EGL_EXTENSIONS. +

+ EGL_NOT_INITIALIZED is generated if + display is a valid but uninitialized + EGLDisplay. +

+ EGL_BAD_PARAMETER is generated if + name is not an accepted value. +
