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