GLPUSHNAME(3gl)GLPUSHNAME(3gl)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 )
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 and is initially empty.
glPushName causes name to be pushed onto the name stack. glPopName
pops one name off the top of the stack.
The maximum name stack depth is implementation-dependent; call
GL_MAX_NAME_STACK_DEPTH to find out the value for a particular imple‐
mentation. 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 the execution of glBegin and the corresponding execution
of 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_SELECT
are 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 exe‐
cuted between a call to glBegin and the corresponding call to glEnd.
