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 obtained for the converted pattern, using the allocator
       in the context if present (or else malloc()), and  the  field  pointed  to  by  buffer  is
       updated.  If  buffer points to a non-NULL field, that must point to a buffer 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 documentation.
