glGetObjectLabel — retrieve the label of a named object identified within a namespace
void glGetObjectLabel(
|
GLenum identifier, |
GLuint name, | |
GLsizei bufSize, | |
GLsizei * length, | |
char * label) ; |
identifier
The namespace from which the name of the object is allocated.
name
The name of the object whose label to retrieve.
bufSize
The length of the buffer whose address is in label
.
length
The address of a variable to receive the length of the object label.
label
The address of a string that will receive the object label.
glGetObjectLabel
retrieves the label of the object identified by
name
within the namespace given by identifier
.
identifier
must be one of GL_BUFFER
, GL_SHADER
,
GL_PROGRAM
, GL_VERTEX_ARRAY
, GL_QUERY
,
GL_PROGRAM_PIPELINE
, GL_TRANSFORM_FEEDBACK
, GL_SAMPLER
,
GL_TEXTURE
, GL_RENDERBUFFER
, GL_FRAMEBUFFER
,
to indicate the namespace containing the names of buffers, shaders, programs, vertex array objects, query objects,
program pipelines, transform feedback objects, samplers, textures, renderbuffers and frame
buffers, respectively.
label
is the address of a string that will be used to store the object label.
bufSize
specifies the number of characters in the array identified by label
.
length
contains the address of a variable which will receive the number of characters in the object label.
If length
is NULL, then it is ignored and no data is written. Likewise, if label
is NULL, or if bufSize
is zero then no data is written to label
.
GL_INVALID_ENUM
is generated if identifier
is not one of the accepted object types.
GL_INVALID_OPERATION
is generated if name
is not the name of an existing object of the type specified by identifier
.
GL_INVALID_VALUE
is generated if bufSize
is
zero.
If not NULL, length
and label
should be addresses
to which the client has write access, otherwise undefined behavior, including process termination
may occur.
glGet with argument GL_MAX_LABEL_LENGTH
