glObjectPtrLabel: label a a sync object identified by a pointer

Function Definition

 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.

Associated Gets
