3df15adc 167
168Escapes at most the first "count" chars of pv and puts the results into
ab3bbdeb 169dsv such that the size of the escaped string will not exceed "max" chars
3df15adc 170and will not contain any incomplete escape sequences.
171
ab3bbdeb 172If flags contains PERL_PV_ESCAPE_QUOTE then any double quotes in the string
173will also be escaped.
3df15adc 174
175Normally the SV will be cleared before the escaped string is prepared,
ab3bbdeb 176but when PERL_PV_ESCAPE_NOCLEAR is set this will not occur.
177
38a44b82 178If PERL_PV_ESCAPE_UNI is set then the input string is treated as Unicode,
ab3bbdeb 179if PERL_PV_ESCAPE_UNI_DETECT is set then the input string is scanned
38a44b82 180using C<is_utf8_string()> to determine if it is Unicode.
ab3bbdeb 181
182If PERL_PV_ESCAPE_ALL is set then all input chars will be output
183using C<\x01F1> style escapes, otherwise only chars above 255 will be
184escaped using this style, other non printable chars will use octal or
185common escaped patterns like C<\n>. If PERL_PV_ESCAPE_NOBACKSLASH
186then all chars below 255 will be treated as printable and
187will be output as literals.
188
189If PERL_PV_ESCAPE_FIRSTCHAR is set then only the first char of the
190string will be escaped, regardles of max. If the string is utf8 and
191the chars value is >255 then it will be returned as a plain hex
192sequence. Thus the output will either be a single char,
193an octal escape sequence, a special escape like C<\n> or a 3 or
194more digit hex value.
3df15adc 195
44a2ac75 196If PERL_PV_ESCAPE_RE is set then the escape char used will be a '%' and
197not a '\\'. This is because regexes very often contain backslashed
198sequences, whereas '%' is not a particularly common character in patterns.
199
