NAME

       scan_cescape - parse C escaped string

SYNTAX

       #include <libowfat/textcode.h>

       size_t scan_cescape(const char *src,char *dest,size_t* destlen);

DESCRIPTION

       scan_cescape parses C escaped text from src into dest.  Parsing stops at the 0 terminator,
       invalid input characters or a double quote that was not escaped.

       C  escape  sequences  like  \n  and  \x0a  and  \012  are  translated  into  their  binary
       counterparts. The C99 escape sequences \u and \U are supported and lead to UTF-8 sequences
       being output.

       scan_cescape will then write the number of bytes in dest into  *destlen,  and  return  the
       number of bytes decoded from src.

       dest can be NULL. destlen can be NULL. dest can be src.

       To  make  sure  dest  is  large  enough,  either  allocate  strlen(src)+1  bytes  or  call
       scan_cescape twice, the first time with dest == NULL (*destlen will still be written).

RETURN VALUE

       scan_cescape returns the number of bytes successfully parsed from src.

EXAMPLES

       scan_cescape("test\n
