.SH NAME
|
|
PCRE2 - Perl-compatible regular expressions (revised API)
|
|
.SH SYNOPSIS
|
|
.rs
|
|
.sp
|
|
.B #include <pcre2.h>
|
|
.PP
|
|
.nf
|
|
.B int32_t pcre2_serialize_get_number_of_codes(const uint8_t *\fIbytes\fP);

|
.SH DESCRIPTION
|
|
.rs
|
|
.sp
|
|
The \fIbytes\fP argument must point to a serialized byte stream that was
|
|
originally created by \fBpcre2_serialize_encode()\fP (though it may have been
|
|
saved on disc or elsewhere in the meantime). The function returns the number of
|
|
serialized patterns in the byte stream, or one of the following negative error
|
|
codes:
|
|
.sp
|
|
PCRE2_ERROR_BADMAGIC mismatch of id bytes in \fIbytes\fP
|
|
PCRE2_ERROR_BADMODE mismatch of variable unit size or PCRE version
|
|
PCRE2_ERROR_NULL the argument is NULL
|
|
.sp
|
|
PCRE2_ERROR_BADMAGIC may mean that the data is corrupt, or that it was compiled
|
|
on a system with different endianness.
