199 =for apidoc pv_escape
201 Escapes at most the first "count" chars of pv and puts the results into
202 dsv such that the size of the escaped string will not exceed "max" chars
203 and will not contain any incomplete escape sequences.
205 If flags contains PERL_PV_ESCAPE_QUOTE then any double quotes in the string
206 will also be escaped.
208 Normally the SV will be cleared before the escaped string is prepared,
209 but when PERL_PV_ESCAPE_NOCLEAR is set this will not occur.
211 If PERL_PV_ESCAPE_UNI is set then the input string is treated as Unicode,
212 if PERL_PV_ESCAPE_UNI_DETECT is set then the input string is scanned
213 using C<is_utf8_string()> to determine if it is Unicode.
215 If PERL_PV_ESCAPE_ALL is set then all input chars will be output
216 using C<\x01F1> style escapes, otherwise only chars above 255 will be
217 escaped using this style, other non printable chars will use octal or
218 common escaped patterns like C<\n>. If PERL_PV_ESCAPE_NOBACKSLASH
219 then all chars below 255 will be treated as printable and
220 will be output as literals.
222 If PERL_PV_ESCAPE_FIRSTCHAR is set then only the first char of the
223 string will be escaped, regardles of max. If the string is utf8 and
224 the chars value is >255 then it will be returned as a plain hex
225 sequence. Thus the output will either be a single char,
226 an octal escape sequence, a special escape like C<\n> or a 3 or
227 more digit hex value.
229 If PERL_PV_ESCAPE_RE is set then the escape char used will be a '%' and
230 not a '\\'. This is because regexes very often contain backslashed
231 sequences, whereas '%' is not a particularly common character in patterns.
233 Returns a pointer to the escaped text as held by dsv.
