glPushName, glPopName

NAME

glPushName, glPopName -- push and pop the name stack

C SPECIFICATION

void glPushName(GLuint name)

PARAMETERS

name
Specifies a name that will be pushed onto the name stack.

C SPECIFICATION

void glPopName(void void)

DESCRIPTION

The name stack is used during selection mode to allow sets of rendering commands to be uniquely identified. It consists of an ordered set of unsigned integers. glPushName causes name to be pushed onto the name stack, which is initially empty. glPopName pops one name off the top of the stack.

It is an error to push a name onto a full stack, or to pop a name off an empty stack. It is also an error to manipulate the name stack between a call to glBegin and the corresponding call to glEnd. In any of these cases, the error flag is set and no other change is made to GL state.

The name stack is always empty while the render mode is not GL_SELECT. Calls to glPushName or glPopName while the render mode is not GL_SELECTare ignored.

ERRORS

GL_STACK_OVERFLOW is generated if glPushName is called while the name stack is full.

GL_STACK_UNDERFLOW is generated if glPopName is called while the name stack is empty.

GL_INVALID_OPERATION is generated if glPushName or glPopName is called between a call to glBegin and the corresponding call to glEnd.

ASSOCIATED GETS

glGet with argument GL_NAME_STACK_DEPTH
glGet with argument GL_MAX_NAME_STACK_DEPTH
