GLPUSHNAME() MachTen Programmer’s Manual GLPUSHNAME()

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 con-
sists of an ordered set of unsigned integers and is ini-
tially 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 implementation. 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 glPop-
Name is executed between a call to glBegin and the corre-
sponding call to glEnd.

ASSOCIATED GETS
glGet with argument GL_NAME_STACK_DEPTH
glGet with argument GL_MAX_NAME_STACK_DEPTH
