168 Escapes at most the first "count" chars of pv and puts the results into
169 dsv such that the size of the escaped string will not exceed "max" chars
170 and will not contain any incomplete escape sequences.
172 If flags contains PERL_PV_ESCAPE_QUOTE then any double quotes in the string
173 will also be escaped.
175 Normally the SV will be cleared before the escaped string is prepared,
176 but when PERL_PV_ESCAPE_NOCLEAR is set this will not occur.
178 If PERL_PV_ESCAPE_UNI is set then the input string is treated as Unicode,
179 if PERL_PV_ESCAPE_UNI_DETECT is set then the input string is scanned
180 using C<is_utf8_string()> to determine if it is Unicode.
182 If PERL_PV_ESCAPE_ALL is set then all input chars will be output
183 using C<\x01F1> style escapes, otherwise only chars above 255 will be
184 escaped using this style, other non printable chars will use octal or
185 common escaped patterns like C<\n>. If PERL_PV_ESCAPE_NOBACKSLASH
186 then all chars below 255 will be treated as printable and
187 will be output as literals.
189 If PERL_PV_ESCAPE_FIRSTCHAR is set then only the first char of the
190 string will be escaped, regardles of max. If the string is utf8 and
191 the chars value is >255 then it will be returned as a plain hex
192 sequence. Thus the output will either be a single char,
193 an octal escape sequence, a special escape like C<\n> or a 3 or
194 more digit hex value.
196 If PERL_PV_ESCAPE_RE is set then the escape char used will be a '%' and
197 not a '\\'. This is because regexes very often contain backslashed
198 sequences, whereas '%' is not a particularly common character in patterns.
200 Returns a pointer to the escaped text as held by dsv.
