## C Specification

void `glObjectPtrLabel` void * ptr GLsizei length const char * label

## Parameters

ptr

  A pointer identifying a sync object.

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

`glObjectPtrLabel` labels the sync object identified by ptr.

label is the address of a string that will be used to label the 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_VALUE` is generated if ptr is not a valid sync object.

`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`.
