.SH DESCRIPTION
|

|
|
|
.rs

|
|
|
|
.sp
|
|
|
|
|
This function encodes a list of compiled patterns into a byte stream that can
|
|
|
|
|
be saved on disc or elsewhere. Its arguments are:
|
|
|
|
|
.sp
|
|
|
|
|
\fIcodes\fP pointer to a vector containing the list
|
|
|
|
|
\fInumber_of_codes\fP number of slots in the vector
|
|
|
|
|
\fIserialized_bytes\fP set to point to the serialized byte stream
|
|
|
|
|
\fIserialized_size\fP set to the number of bytes in the byte stream
|
|
|
|
|
\fIgcontext\fP pointer to a general context or NULL
|
|
|
|
|
.sp
|
|
|
|
|
The context argument is used to obtain memory for the byte stream. When the
|
|
|
|
|
serialized data is no longer needed, it must be freed by calling
|
|
|
|
|
\fBpcre2_serialize_free()\fP. The yield of the function is the number of
|
|
|
|
|
serialized patterns, or one of the following negative error codes:
|
|
|
|
|
.sp
|
|
|
|
|
PCRE2_ERROR_BADDATA \fInumber_of_codes\fP is zero or less
|
|
|
|
|
PCRE2_ERROR_BADMAGIC mismatch of id bytes in one of the patterns
|
|
|
|
|
PCRE2_ERROR_MEMORY memory allocation failed
|
|
|
|
|
PCRE2_ERROR_MIXEDTABLES the patterns do not all use the same tables
|
|
|
|
|
PCRE2_ERROR_NULL an argument other than \fIgcontext\fP is NULL
|
|
|
|
|
.sp
|
|
|
|
|
PCRE2_ERROR_BADMAGIC means either that a pattern's code has been corrupted, or
|
|
|
|
|
that a slot in the vector does not point to a compiled pattern.
