ERR_set_mark(3) OpenSSL ERR_set_mark(3)NAME
ERR_set_mark, ERR_pop_to_mark - set marks and pop errors until mark
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.
SEE ALSO err(3)HISTORY
ERR_set_mark() and ERR_pop_to_mark() were added in OpenSSL 0.9.8.
1.0.1e 2013-02-11 ERR_set_mark(3)

GLPUSHNAME(3G)GLPUSHNAME(3G)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
