Hi!
I know that the 'TSRMLS' is an abbreviation of 'Thread Safe Resource Manager 
Local Storage', but what means is 'CC' and 'DC' in the 'TSRMLS_CC' and 
'TSRMLS_DC' ?

This has been asked multiple times before on this list, but once again:

_CC - call with comma
_C  - call (without comma)
_DC - declaration with comma
_D  - declaration (w/o comma)
