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.
