97 | Escapes at most the first "count" chars of pv and puts the results into | |
ab3bbdeb | 98 | dsv such that the size of the escaped string will not exceed "max" chars |
3df15adc YO |
99 | and will not contain any incomplete escape sequences. |
100 | ||
ab3bbdeb YO |
101 | If flags contains PERL_PV_ESCAPE_QUOTE then any double quotes in the string |
102 | will also be escaped. | |
3df15adc YO |
103 | |
104 | Normally the SV will be cleared before the escaped string is prepared, | |
ab3bbdeb YO |
105 | but when PERL_PV_ESCAPE_NOCLEAR is set this will not occur. |
106 | ||
38a44b82 | 107 | If PERL_PV_ESCAPE_UNI is set then the input string is treated as Unicode, |
ab3bbdeb | 108 | if PERL_PV_ESCAPE_UNI_DETECT is set then the input string is scanned |
38a44b82 | 109 | using C<is_utf8_string()> to determine if it is Unicode. |
ab3bbdeb YO |
110 | |
111 | If PERL_PV_ESCAPE_ALL is set then all input chars will be output | |
681f01c2 | 112 | using C<\x01F1> style escapes, otherwise if PERL_PV_ESCAPE_NONASCII is set, only |
951cbe24 | 113 | non-ASCII chars will be escaped using this style; otherwise, only chars above |
681f01c2 | 114 | 255 will be so escaped; other non printable chars will use octal or |
72d33970 FC |
115 | common escaped patterns like C<\n>. |
116 | Otherwise, if PERL_PV_ESCAPE_NOBACKSLASH | |
681f01c2 | 117 | then all chars below 255 will be treated as printable and |
ab3bbdeb YO |
118 | will be output as literals. |
119 | ||
120 | If PERL_PV_ESCAPE_FIRSTCHAR is set then only the first char of the | |
72d33970 | 121 | string will be escaped, regardless of max. If the output is to be in hex, |
c8536afa | 122 | then it will be returned as a plain hex |
72d33970 | 123 | sequence. Thus the output will either be a single char, |
c8536afa | 124 | an octal escape sequence, a special escape like C<\n> or a hex value. |
3df15adc | 125 | |
44a2ac75 | 126 | If PERL_PV_ESCAPE_RE is set then the escape char used will be a '%' and |
72d33970 | 127 | not a '\\'. This is because regexes very often contain backslashed |
44a2ac75 YO |
128 | sequences, whereas '%' is not a particularly common character in patterns. |
