PCRE2_PATTERN_CONVERT(3)   Library Functions Manual   PCRE2_PATTERN_CONVERT(3)

NAME
       PCRE2 - Perl-compatible regular expressions (revised API)

SYNOPSIS

       #include <pcre2.h>

       int pcre2_pattern_convert(PCRE2_SPTR pattern, PCRE2_SIZE length,
         uint32_t options, PCRE2_UCHAR **buffer,
         PCRE2_SIZE *blength, pcre2_convert_context *cvcontext);

DESCRIPTION

       This  function  is  part  of  an experimental set of pattern conversion
       functions.  It converts a foreign pattern (for example, a glob) into  a
       PCRE2 regular expression pattern. Its arguments are:

         pattern     The foreign pattern
         length      The length of the input pattern or PCRE2_ZERO_TERMINATED
         options     Option bits
         buffer      Pointer to pointer to output buffer, or NULL
         blength     Pointer to output length field
         cvcontext   Pointer to a convert context or NULL

       The length of the converted pattern (excluding the terminating zero) is
       returned via blength. If buffer is NULL, the function just returns  the
       output  length.  If buffer points to a NULL pointer, heap memory is ob-
       tained for the converted pattern, using the allocator in the context if
       present  (or  else malloc()), and the field pointed to by buffer is up-
       dated. If buffer points to a non-NULL field, that must point to a  buf-
       fer  whose size is in the variable pointed to by blength. This value is
       updated.

       The option bits are:

         PCRE2_CONVERT_UTF                     Input is UTF
         PCRE2_CONVERT_NO_UTF_CHECK            Do not check UTF validity
         PCRE2_CONVERT_POSIX_BASIC             Convert POSIX basic pattern
         PCRE2_CONVERT_POSIX_EXTENDED          Convert POSIX extended pattern
         PCRE2_CONVERT_GLOB                    ) Convert
         PCRE2_CONVERT_GLOB_NO_WILD_SEPARATOR  )   various types
         PCRE2_CONVERT_GLOB_NO_STARSTAR        )     of glob

       The return value from pcre2_pattern_convert() is zero on success  or  a
       non-zero PCRE2 error code.

       The pattern conversion functions are described in the pcre2convert doc-
       umentation.
