| =for apidoc pv_escape |
| |
| Escapes at most the first "count" chars of pv and puts the results into |
| dsv such that the size of the escaped string will not exceed "max" chars |
| and will not contain any incomplete escape sequences. |
| |
| If flags contains PERL_PV_ESCAPE_QUOTE then any double quotes in the string |
| will also be escaped. |
| |
| Normally the SV will be cleared before the escaped string is prepared, |
| but when PERL_PV_ESCAPE_NOCLEAR is set this will not occur. |
| |
| If PERL_PV_ESCAPE_UNI is set then the input string is treated as Unicode, |
| if PERL_PV_ESCAPE_UNI_DETECT is set then the input string is scanned |
| using C<is_utf8_string()> to determine if it is Unicode. |
| |
| If PERL_PV_ESCAPE_ALL is set then all input chars will be output |
| using C<\x01F1> style escapes, otherwise if PERL_PV_ESCAPE_NONASCII is set, only |
| chars above 127 will be escaped using this style; otherwise, only chars above |
| 255 will be so escaped; other non printable chars will use octal or |
| common escaped patterns like C<\n>. Otherwise, if PERL_PV_ESCAPE_NOBACKSLASH |
| then all chars below 255 will be treated as printable and |
| will be output as literals. |
| |
| If PERL_PV_ESCAPE_FIRSTCHAR is set then only the first char of the |
| string will be escaped, regardless of max. If the output is to be in hex, |
| then it will be returned as a plain hex |
| sequence. Thus the output will either be a single char, |
| an octal escape sequence, a special escape like C<\n> or a hex value. |
| |
| If PERL_PV_ESCAPE_RE is set then the escape char used will be a '%' and |
| not a '\\'. This is because regexes very often contain backslashed |
| sequences, whereas '%' is not a particularly common character in patterns. |
| |
| Returns a pointer to the escaped text as held by dsv. |
