glObjectLabel 3G
glObjectLabel label a named object identified within a namespace

## C Specification

void `glObjectLabel` GLenum identifier GLuint name GLsizei length const char * label

## Parameters

identifier

  The namespace from which the name of the object is allocated.

name

  The name of the object to label.

length

  The length of the label to be used for the object.

label

  The address of a string containing the label to assign to the object.

## Description

`glObjectLabel` labels 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 label an object. length contains the number of characters in label. If length is negative, it is implied that label contains a null-terminated string. If label is NULL, any debug label is effectively removed from the object.

## 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 the number of characters in label, excluding the null terminator when length is negative, is greater than the value of `GL_MAX_LABEL_LENGTH`.

## Associated Gets

glGet with argument `GL_MAX_LABEL_LENGTH`.
