PCRE_UTF16_TO_HOST_BYTE_ORDER(3)			     Library Functions Manual				  PCRE_UTF16_TO_HOST_BYTE_ORDER(3)

NAME

       PCRE - Perl-compatible regular expressions

SYNOPSIS


       #include <pcre.h>

       int pcre16_utf16_to_host_byte_order(PCRE_UCHAR16 *output,
	    PCRE_SPTR16 input, int length, int *host_byte_order,
	    int keep_boms);

DESCRIPTION


       This  function, which exists only in the 16-bit library, converts a UTF-16 string to the correct order for the current host, taking account
       of any byte order marks (BOMs) within the string. Its arguments are:

	 output 	  pointer to output buffer, may be the same as input
	 input		  pointer to input buffer
	 length 	  number of 16-bit units in the input, or negative for
			    a zero-terminated string
	 host_byte_order  a NULL value or a non-zero value pointed to means
			    start in host byte order
	 keep_boms	  if non-zero, BOMs are copied to the output string

       The result of the function is the number of 16-bit units placed into the output buffer, including the zero terminator  if  the  string  was
       zero-terminated.

       If host_byte_order is not NULL, it is set to indicate the byte order that is current at the end of the string.

       There is a complete description of the PCRE native API in the pcreapi page and a description of the POSIX API in the pcreposix page.

PCRE_COPY_NAMED_SUBSTRING(3)				     Library Functions Manual				      PCRE_COPY_NAMED_SUBSTRING(3)

NAME

       PCRE - Perl-compatible regular expressions

SYNOPSIS


       #include <pcre.h>

       int pcre_copy_named_substring(const pcre *code,
	    const char *subject, int *ovector,
	    int stringcount, const char *stringname,
	    char *buffer, int buffersize);

       int pcre16_copy_named_substring(const pcre16 *code,
	    PCRE_SPTR16 subject, int *ovector,
	    int stringcount, PCRE_SPTR16 stringname,
	    PCRE_UCHAR16 *buffer, int buffersize);

       int pcre32_copy_named_substring(const pcre32 *code,
	    PCRE_SPTR32 subject, int *ovector,
	    int stringcount, PCRE_SPTR32 stringname,
	    PCRE_UCHAR32 *buffer, int buffersize);

DESCRIPTION


       This is a convenience function for extracting a captured substring, identified by name, into a given buffer. The arguments are:

	 code	       Pattern that was successfully matched
	 subject       Subject that has been successfully matched
	 ovector       Offset vector that pcre[16|32]_exec() used
	 stringcount   Value returned by pcre[16|32]_exec()
	 stringname    Name of the required substring
	 buffer        Buffer to receive the string
	 buffersize    Size of buffer

       The  yield is the length of the substring, PCRE_ERROR_NOMEMORY if the buffer was too small, or PCRE_ERROR_NOSUBSTRING if the string name is
       invalid.

       There is a complete description of the PCRE native API in the pcreapi page and a description of the POSIX API in the pcreposix page.
