3df15adc
YO
219
220Escapes at most the first "count" chars of pv and puts the results into
ab3bbdeb 221dsv such that the size of the escaped string will not exceed "max" chars
3df15adc
YO
222and will not contain any incomplete escape sequences.
223
ab3bbdeb
YO
224If flags contains PERL_PV_ESCAPE_QUOTE then any double quotes in the string
225will also be escaped.
3df15adc
YO
226
227Normally the SV will be cleared before the escaped string is prepared,
ab3bbdeb
YO
228but when PERL_PV_ESCAPE_NOCLEAR is set this will not occur.
229
38a44b82 230If PERL_PV_ESCAPE_UNI is set then the input string is treated as Unicode,
ab3bbdeb 231if PERL_PV_ESCAPE_UNI_DETECT is set then the input string is scanned
38a44b82 232using C<is_utf8_string()> to determine if it is Unicode.
ab3bbdeb
YO
233
234If PERL_PV_ESCAPE_ALL is set then all input chars will be output
235using C<\x01F1> style escapes, otherwise only chars above 255 will be
236escaped using this style, other non printable chars will use octal or
237common escaped patterns like C<\n>. If PERL_PV_ESCAPE_NOBACKSLASH
238then all chars below 255 will be treated as printable and
239will be output as literals.
240
241If PERL_PV_ESCAPE_FIRSTCHAR is set then only the first char of the
242string will be escaped, regardles of max. If the string is utf8 and
243the chars value is >255 then it will be returned as a plain hex
244sequence. Thus the output will either be a single char,
245an octal escape sequence, a special escape like C<\n> or a 3 or
246more digit hex value.
3df15adc 247
44a2ac75
YO
248If PERL_PV_ESCAPE_RE is set then the escape char used will be a '%' and
249not a '\\'. This is because regexes very often contain backslashed
250sequences, whereas '%' is not a particularly common character in patterns.
