NAME
glGetObjectLabel - retrieve the label of a named object identified
within a namespace
C SPECIFICATION
void glGetObjectLabel(GLenum identifier, GLuint name, GLsizei bifSize,
GLsizei * length, char * label);
PARAMETERS
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.
DESCRIPTION
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 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.
ERRORS
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.
ASSOCIATED GETS
glGet() with argument GL_MAX_LABEL_LENGTH.
