  26. .SH DESCRIPTION
  27. .rs
  28. .sp
  29. This function compiles a regular expression into an internal form. It is the
  30. same as \fBpcre[16|32]_compile()\fP, except for the addition of the
  31. \fIerrorcodeptr\fP argument. The arguments are:
  32. .
  33. .sp
  34. \fIpattern\fP A zero-terminated string containing the
  35. regular expression to be compiled
  36. \fIoptions\fP Zero or more option bits
  37. \fIerrorcodeptr\fP Where to put an error code
  38. \fIerrptr\fP Where to put an error message
  39. \fIerroffset\fP Offset in pattern where error was found
  40. \fItableptr\fP Pointer to character tables, or NULL to
  41. use the built-in default
  42. .sp
  43. The option bits are:
  44. .sp
  45. PCRE_ANCHORED Force pattern anchoring
  46. PCRE_AUTO_CALLOUT Compile automatic callouts
  47. PCRE_BSR_ANYCRLF \eR matches only CR, LF, or CRLF
  48. PCRE_BSR_UNICODE \eR matches all Unicode line endings
  49. PCRE_CASELESS Do caseless matching
  50. PCRE_DOLLAR_ENDONLY $ not to match newline at end
  51. PCRE_DOTALL . matches anything including NL
  52. PCRE_DUPNAMES Allow duplicate names for subpatterns
  53. PCRE_EXTENDED Ignore white space and # comments
  54. PCRE_EXTRA PCRE extra features
  55. (not much use currently)
  56. PCRE_FIRSTLINE Force matching to be before newline
  57. PCRE_JAVASCRIPT_COMPAT JavaScript compatibility
  58. PCRE_MULTILINE ^ and $ match newlines within data
  59. PCRE_NEVER_UTF Lock out UTF, e.g. via (*UTF)
  60. PCRE_NEWLINE_ANY Recognize any Unicode newline sequence
  61. PCRE_NEWLINE_ANYCRLF Recognize CR, LF, and CRLF as newline
  62. sequences
  63. PCRE_NEWLINE_CR Set CR as the newline sequence
  64. PCRE_NEWLINE_CRLF Set CRLF as the newline sequence
  65. PCRE_NEWLINE_LF Set LF as the newline sequence
  66. PCRE_NO_AUTO_CAPTURE Disable numbered capturing paren-
  67. theses (named ones available)
  68. PCRE_NO_AUTO_POSSESS Disable auto-possessification
  69. PCRE_NO_START_OPTIMIZE Disable match-time start optimizations
  70. PCRE_NO_UTF16_CHECK Do not check the pattern for UTF-16
  71. validity (only relevant if
  72. PCRE_UTF16 is set)
  73. PCRE_NO_UTF32_CHECK Do not check the pattern for UTF-32
  74. validity (only relevant if
  75. PCRE_UTF32 is set)
  76. PCRE_NO_UTF8_CHECK Do not check the pattern for UTF-8
  77. validity (only relevant if
  78. PCRE_UTF8 is set)
  79. PCRE_UCP Use Unicode properties for \ed, \ew, etc.
  80. PCRE_UNGREEDY Invert greediness of quantifiers
  81. PCRE_UTF16 Run \fBpcre16_compile()\fP in UTF-16 mode
  82. PCRE_UTF32 Run \fBpcre32_compile()\fP in UTF-32 mode
  83. PCRE_UTF8 Run \fBpcre_compile()\fP in UTF-8 mode
  84. .sp
  85. PCRE must be built with UTF support in order to use PCRE_UTF8/16/32 and
  86. PCRE_NO_UTF8/16/32_CHECK, and with UCP support if PCRE_UCP is used.
  87. .P
  88. The yield of the function is a pointer to a private data structure that
  89. contains the compiled pattern, or NULL if an error was detected. Note that
  90. compiling regular expressions with one version of PCRE for use with a different
  91. version is not guaranteed to work and may cause crashes.
