Function Documentation

FindStringInExtensionList()

const char* FindStringInExtensionList	(	const char *	string,
		const char *	substring
	)

Find a substring in a string made of space delimited elements.

The substring has to match the complete element, partial matches don't count.

Parameters

string	List of space delimited elements.
substring	Substring to find.

Returns

Pointer to the start of the match or nullptr if the substring is not present.

IsOpenGLVersionAtLeast()

bool IsOpenGLVersionAtLeast	(	uint8_t	major,
		uint8_t	minor
	)

Check if the current OpenGL version is equal or higher than a given one.

Parameters

major	Minimal major version.
minor	Minimal minor version.

Precondition

OpenGL was initialized.

Returns

True if the OpenGL version is equal or higher than the requested one.
