<chapter id="libpq">

<title><application>libpq</application> - C Library</title>

<function>PQescapeBytea</function>,

<function>PQunescapeBytea</function>,

and <function>PQnotifies</function>.

- It is needed by Microsoft Windows, which cannot free memory across

- DLLs, unless multithreaded DLLs (<option>/MD</option> in VC6) are used.

- On other platforms, this function is the same as the standard library function <function>free()</>.

+ It is particularly important that this function, rather than

+ <function>free()</>, be used on Microsoft Windows. This is because

+ allocating memory in a DLL and releasing it in the application works

+ only if multithreaded/single-threaded, release/debug, and static/dynamic

+ flags are the same for the DLL and the application. On non-Microsoft

+ Windows platforms, this function is the same as the standard library

+ function <function>free()</>.
