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 func- tions. 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 re- turned 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 vari- able 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 documen- tation. PCRE2 10.47 12 July 2017 PCRE2_PATTERN_CONVERT(3)
