70 This simply passes the C representation of the Perl variable (an SV*)
71 in and out of the XS layer. This can be used if the C code wants
203 A signed integer. This is cast to the required  integer type when
218 A signed integer. This typemap converts the Perl value to a native
245 A boolean type. This can be used to pass true and false values to and
260 This is for unsigned integers. It is equivalent to using T_UV
266 Short integers. This is equivalent to T_IV but explicitly casts
272 Unsigned short integers. This is equivalent to T_UV but explicitly
291 Long integers. This is equivalent to T_IV but explicitly casts
297 Unsigned long integers. This is equivalent to T_UV but explicitly

722 This is used to convert the perl argument list to a C array
742 array. This is used to determine how many elements should be pushed
743 onto the return argument stack. This is not required on input since
