2013 Khronos Group glGetObjectPtrLabel 3G glGetObjectPtrLabel retrieve the label of a sync object identified by a pointer void glGetObjectPtrLabel void * ptr GLsizei bifSize GLsizei * length char * label ptr The name of the sync 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. glGetObjectPtrLabel retrieves the label of the sync object identified by ptr. 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. GL_INVALID_ENUM is generated if identifier is not one of the accepted object types. GL_INVALID_VALUE is generated if ptr is not the name of an existing sync object. 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. glGet with argument GL_MAX_LABEL_LENGTH. glPushDebugGroup, glPopDebugGroup, glObjectLabel, glGetObjectLabel.
