-== NAME
-
-nng_strdup - duplicate string
-
-== SYNOPSIS
-
-[source, c]
-----
-#include <nng/nng.h>
-
-char *nng_strdup(const char *src);
-----
-
-== DESCRIPTION
-
-The `nng_strdup()` duplicates the string _src_ and returns it.
-
-This is logically equivalent to using xref:nng_alloc.3.adoc[`nng_alloc()`]
-to allocate a region of memory of `strlen(s) + 1` bytes, and then
-using `strcpy()` to copy the string into the destination before
-returning it.
-
-The returned string should be deallocated with
-xref:nng_strfree.3.adoc[`nng_strfree()`], or may be deallocated using the
-xref:nng_free.3.adoc[`nng_free()`] using the length of the returned string plus
-one (for the `NUL` terminating byte).
-
-IMPORTANT: Do not use the system `free()` or similar functions to deallocate
-the string, since those may use a different memory arena!
-
-== RETURN VALUES
-
-This function returns the new string on success, and `NULL` on failure.
-
-== ERRORS
-
-No errors are returned, but a `NULL` return value should be
-treated the same as `NNG_ENOMEM`.

-== NAME
-
-nng_strfree - free memory
-
-== SYNOPSIS
-
-[source, c]
-----
-#include <nng/nng.h>
-
-void nng_strfree(char *str);
-----
-
-== DESCRIPTION
-
-The `nng_strfree()` function deallocates the string _str_.
-This is equivalent to using xref:nng_free.3.adoc[`nng_free()`] with
-the length of _str_ plus one (for the `NUL` terminating byte) as
-the size.
-
-IMPORTANT: This should only be used with strings that were allocated
-by xref:nng_strdup.3.adoc[`nng_strdup()`] or
-xref:nng_alloc.3.adoc[`nng_alloc()`].
-In all cases, the allocation size of the string must be the same
-as `strlen(__str__) + 1`.
-
-IMPORTANT: Consequently, if the a string created with
-xref:nng_strdup.3.adoc[`nng_strdup()`] is modified to be shorter, then
-it is incorrect to call this function.
-(The xref:nng_free.3.adoc[`nng_free()`] function can be used instead in that
-case, using the length of the original string plus one for the size.)
-
-== RETURN VALUES

-None.
