443Tells an SV that it is an integer and disables all other OK bits.
444
e331fc52 445=for apidoc Am|void|SvIOK_only_UV|SV* sv
446Tells and SV that it is an unsigned integer and disables all other OK bits.
447
448=for apidoc Am|void|SvIOK_UV|SV* sv
449Returns a boolean indicating whether the SV contains an unsigned integer.
450

453
e331fc52 454=for apidoc Am|void|SvIOK_notUV|SV* sv
455Returns a boolean indicating whether the SV contains an signed integer.
456

458Returns a boolean indicating whether the SV contains a double.
459
460=for apidoc Am|void|SvNOK_on|SV* sv
461Tells an SV that it is a double.
462
463=for apidoc Am|void|SvNOK_off|SV* sv
464Unsets the NV status of an SV.

483Returns a boolean indicating whether the SvIVX is a valid offset value for
484the SvPVX. This hack is used internally to speed up removal of characters
485from the beginning of a SvPV. When SvOOK is true, then the start of the
486allocated string buffer is really (SvPVX - SvIVX).

506true.

510true.
511
512=for apidoc Am|char*|SvPVX|SV* sv
513Returns a pointer to the string in the SV. The SV must contain a
514string.
515
516=for apidoc Am|STRLEN|SvCUR|SV* sv
517Returns the length of the string which is in the SV. See C<SvLEN>.
518
519=for apidoc Am|STRLEN|SvLEN|SV* sv
659239a4 520Returns the size of the string buffer in the SV, not including any part
521attributable to C<SvOOK>. See C<SvCUR>.
954c1994 522
523=for apidoc Am|char*|SvEND|SV* sv
524Returns a pointer to the last character in the string which is in the SV.
525See C<SvCUR>. Access the character as *(SvEND(sv)).
