GLDELETESHADER(3G) OpenGL 3.3 GLDELETESHADER(3G)NAME
glDeleteShader - Deletes a shader object
C SPECIFICATION
void glDeleteShader(GLuint shader);
PARAMETERS
shader
Specifies the shader object to be deleted.
DESCRIPTION
glDeleteShader frees the memory and invalidates the name associated with the shader object specified by shader. This command effectively
undoes the effects of a call to glCreateShader().
If a shader object to be deleted is attached to a program object, it will be flagged for deletion, but it will not be deleted until it is
no longer attached to any program object, for any rendering context (i.e., it must be detached from wherever it was attached before it will
be deleted). A value of 0 for shader will be silently ignored.
To determine whether an object has been flagged for deletion, call glGetShader() with arguments shader and GL_DELETE_STATUS.
ERRORS
GL_INVALID_VALUE is generated if shader is not a value generated by OpenGL.
ASSOCIATED GETS
glGetAttachedShaders() with the program object to be queried
glGetShader() with arguments shader and GL_DELETE_STATUS
glIsShader()
SEE ALSO

glDetachShader - Detaches a shader object from a program object to which it is attached
C SPECIFICATION
void glDetachShader(GLuint program, GLuint shader);
PARAMETERS
program
Specifies the program object from which to detach the shader object.
shader
Specifies the shader object to be detached.
DESCRIPTION
glDetachShader detaches the shader object specified by shader from the program object specified by program. This command can be used to
undo the effect of the command glAttachShader().
If shader has already been flagged for deletion by a call to glDeleteShader() and it is not attached to any other program object, it will
be deleted after it has been detached.
ERRORS
GL_INVALID_VALUE is generated if either program or shader is a value that was not generated by OpenGL.
GL_INVALID_OPERATION is generated if program is not a program object.
GL_INVALID_OPERATION is generated if shader is not a shader object.
GL_INVALID_OPERATION is generated if shader is not attached to program.
ASSOCIATED GETS
glGetAttachedShaders() with the handle of a valid program object
glGetShader() with arguments shader and GL_DELETE_STATUS
glIsProgram()
glIsShader()
SEE ALSO
glAttachShader()

OS: Solaris 8
I deleted a large file (around 13 Gigs) from my system.
But the output of df -k remains the same. The
capacity % is constant. However one strange thing
is happening- My available space is decreasing, my used
space in increasing (The opposite should happen).
This is happening... (2 Replies)
I always thought that deleted text get stacked in the register. Then I can use '<x>p' to undelete, where <x> the number of the nth deletion. But when I try this it seems that only the last delete action get stored. Am I missing some kind of setting? (3 Replies)
