97 | Escapes at most the first C<count> chars of C<pv> and puts the results into |
98 | C<dsv> such that the size of the escaped string will not exceed C<max> chars | |
9a63e366 | 99 | and will not contain any incomplete escape sequences. The number of bytes |
796b6530 KW |
100 | escaped will be returned in the C<STRLEN *escaped> parameter if it is not null. |
101 | When the C<dsv> parameter is null no escaping actually occurs, but the number | |
4420a417 | 102 | of bytes that would be escaped were it not null will be calculated. |
3df15adc | 103 | |
796b6530 | 104 | If flags contains C<PERL_PV_ESCAPE_QUOTE> then any double quotes in the string |
ab3bbdeb | 105 | will also be escaped. |
3df15adc YO |
106 | |
107 | Normally the SV will be cleared before the escaped string is prepared, | |
796b6530 | 108 | but when C<PERL_PV_ESCAPE_NOCLEAR> is set this will not occur. |
ab3bbdeb | 109 | |
796b6530 KW |
110 | If C<PERL_PV_ESCAPE_UNI> is set then the input string is treated as UTF-8 |
111 | if C<PERL_PV_ESCAPE_UNI_DETECT> is set then the input string is scanned | |
e5860534 | 112 | using C<is_utf8_string()> to determine if it is UTF-8. |
ab3bbdeb | 113 | |
796b6530 KW |
114 | If C<PERL_PV_ESCAPE_ALL> is set then all input chars will be output |
115 | using C<\x01F1> style escapes, otherwise if C<PERL_PV_ESCAPE_NONASCII> is set, only | |
951cbe24 | 116 | non-ASCII chars will be escaped using this style; otherwise, only chars above |
681f01c2 | 117 | 255 will be so escaped; other non printable chars will use octal or |
72d33970 | 118 | common escaped patterns like C<\n>. |
796b6530 | 119 | Otherwise, if C<PERL_PV_ESCAPE_NOBACKSLASH> |
681f01c2 | 120 | then all chars below 255 will be treated as printable and |
ab3bbdeb YO |
121 | will be output as literals. |
122 | ||
796b6530 | 123 | If C<PERL_PV_ESCAPE_FIRSTCHAR> is set then only the first char of the |
72d33970 | 124 | string will be escaped, regardless of max. If the output is to be in hex, |
c8536afa | 125 | then it will be returned as a plain hex |
72d33970 | 126 | sequence. Thus the output will either be a single char, |
c8536afa | 127 | an octal escape sequence, a special escape like C<\n> or a hex value. |
3df15adc | 128 | |
796b6530 KW |
129 | If C<PERL_PV_ESCAPE_RE> is set then the escape char used will be a C<"%"> and |
130 | not a C<"\\">. This is because regexes very often contain backslashed | |
131 | sequences, whereas C<"%"> is not a particularly common character in patterns. | |
44a2ac75 | 132 | |
796b6530 | 133 | Returns a pointer to the escaped text as held by C<dsv>. |
