RETURNS
|
The <<iconv>> function returns the number of non-identical conversions
|
The <<iconv>> function returns the number of non-identical conversions

performed. If an error occurs, (size_t)-1 is returned and <<errno>>
|
performed. If an error occurs, (size_t)-1 is returned and <<errno>>
|
is set appropriately. The values of <[inleft]>, <[in]>, <[out]>,
|
is set appropriately. The values of <[inleft]>, <[in]>, <[out]>,
|
and <[outleft]> are modified to indicate how much input was processed
