# FIX: https://github.com/hsoft/send2trash/issues/17
|
||
|
# Starting in python 3.6.3 it is no longer possible to use:
|
||
|
# LPCWSTR(path + '\0') directly as embedded null characters are no longer
|
||
|
# allowed in strings
|
||
|
# Workaround
|
||
|
# - create buffer of c_wchar[] (LPCWSTR is based on this type)
|
||
|
# - buffer is two c_wchar characters longer (double null terminator)
|
||
|
# - cast the address of the buffer to a LPCWSTR
|
||
|
# NOTE: based on how python allocates memory for these types they should
|
||
|
# always be zero, if this is ever not true we can go back to explicitly
|
||
|
# setting the last two characters to null using buffer[index] = '\0'.
