/**
* stringprep_strerror:
* @rc: a #Stringprep_rc return code.
*
* Convert a return code integer to a text string. This string can be
* used to output a diagnostic message to the user.
*
* STRINGPREP_OK: Successful operation. This value is guaranteed to
* always be zero, the remaining ones are only guaranteed to hold
* non-zero values, for logical comparison purposes.
* STRINGPREP_CONTAINS_UNASSIGNED: String contain unassigned Unicode
* code points, which is forbidden by the profile.
* STRINGPREP_CONTAINS_PROHIBITED: String contain code points
* prohibited by the profile.
* STRINGPREP_BIDI_BOTH_L_AND_RAL: String contain code points with
* conflicting bidirection category.
* STRINGPREP_BIDI_LEADTRAIL_NOT_RAL: Leading and trailing character
* in string not of proper bidirectional category.
* STRINGPREP_BIDI_CONTAINS_PROHIBITED: Contains prohibited code
* points detected by bidirectional code.
* STRINGPREP_TOO_SMALL_BUFFER: Buffer handed to function was too
* small. This usually indicate a problem in the calling
* application.
* STRINGPREP_PROFILE_ERROR: The stringprep profile was inconsistent.
* This usually indicate an internal error in the library.
* STRINGPREP_FLAG_ERROR: The supplied flag conflicted with profile.
* This usually indicate a problem in the calling application.
* STRINGPREP_UNKNOWN_PROFILE: The supplied profile name was not
* known to the library.
* STRINGPREP_ICONV_ERROR: Character encoding conversion error.
* STRINGPREP_NFKC_FAILED: The Unicode NFKC operation failed. This
* usually indicate an internal error in the library.
* STRINGPREP_MALLOC_ERROR: The malloc() was out of memory. This is
* usually a fatal error.
*
* Return value: Returns a pointer to a statically allocated string
* containing a description of the error with the return code @rc.
