glObjectPtrLabel — label a a sync object identified by a pointer

C Specification

void glObjectPtrLabel( void * ptr,
  GLsizei length,
  const char * label);



A pointer identifying a sync object.


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


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


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.


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.
