GLOBJECTPTRLABEL(3G) OpenGL Manual GLOBJECTPTRLABEL(3G) NAME
glObjectPtrLabel - label a a sync object identified by a pointer 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. SEE ALSO
