3df15adc
YO
175
176Escapes at most the first "count" chars of pv and puts the results into
ab3bbdeb 177dsv such that the size of the escaped string will not exceed "max" chars
3df15adc
YO
178and will not contain any incomplete escape sequences.
179
ab3bbdeb
YO
180If flags contains PERL_PV_ESCAPE_QUOTE then any double quotes in the string
181will also be escaped.
3df15adc
YO
182
183Normally the SV will be cleared before the escaped string is prepared,
ab3bbdeb
YO
184but when PERL_PV_ESCAPE_NOCLEAR is set this will not occur.
185
38a44b82 186If PERL_PV_ESCAPE_UNI is set then the input string is treated as Unicode,
ab3bbdeb 187if PERL_PV_ESCAPE_UNI_DETECT is set then the input string is scanned
38a44b82 188using C<is_utf8_string()> to determine if it is Unicode.
ab3bbdeb
YO
189
190If PERL_PV_ESCAPE_ALL is set then all input chars will be output
191using C<\x01F1> style escapes, otherwise only chars above 255 will be
192escaped using this style, other non printable chars will use octal or
193common escaped patterns like C<\n>. If PERL_PV_ESCAPE_NOBACKSLASH
194then all chars below 255 will be treated as printable and
195will be output as literals.
196
197If PERL_PV_ESCAPE_FIRSTCHAR is set then only the first char of the
198string will be escaped, regardles of max. If the string is utf8 and
199the chars value is >255 then it will be returned as a plain hex
200sequence. Thus the output will either be a single char,
201an octal escape sequence, a special escape like C<\n> or a 3 or
202more digit hex value.
3df15adc 203
44a2ac75
YO
204If PERL_PV_ESCAPE_RE is set then the escape char used will be a '%' and
205not a '\\'. This is because regexes very often contain backslashed
206sequences, whereas '%' is not a particularly common character in patterns.
