ERR_set_mark(3) 						      OpenSSL							   ERR_set_mark(3)

NAME

       ERR_set_mark, ERR_pop_to_mark - set marks and pop errors until mark

LIBRARY

       libcrypto, -lcrypto

SYNOPSIS

	#include <openssl/err.h>

	int ERR_set_mark(void);

	int ERR_pop_to_mark(void);

DESCRIPTION

       ERR_set_mark() sets a mark on the current topmost error record if there is one.

       ERR_pop_to_mark() will pop the top of the error stack until a mark is found.  The mark is then removed.	If there is no mark, the whole
       stack is removed.

RETURN VALUES

       ERR_set_mark() returns 0 if the error stack is empty, otherwise 1.

       ERR_pop_to_mark() returns 0 if there was no mark in the error stack, which implies that the stack became empty, otherwise 1.

HISTORY

       ERR_set_mark() and ERR_pop_to_mark() were added in OpenSSL 0.9.8.

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  implementa-
       tion.  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 executed 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
