glGetObjectLabel 3G
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`.
