[TYPO3] mysql function

[Nino Katic]

Hello,

Does anybody know where is declaration for mysql function that is used in 
one of Typo3 extensions i'm using or this is some internal php function? I 
need to debug something and i can't find the source of mysql function. It is 
mentioned in 
http://typo3.org/documentation/document-library/core-documentation/doc_core_cgl/4.1.0/view/1/4/ 
but can't find it anywhere in Typo3 source :-( Thx.

Regards,

Nino
