int pcre_pattern_to_host_byte_order(pcre *code, pcre_extra *extra, const unsigned char *tables); int pcre16_pattern_to_host_byte_order(pcre16 *code, pcre16_extra *extra, const unsigned char *tables); int pcre32_pattern_to_host_byte_order(pcre32 *code, pcre32_extra *extra, const unsigned char *tables);
This function ensures that the bytes in 2-byte and 4-byte values in a compiled pattern are in the correct order for the current host. It is useful when a pattern that has been compiled on one host is transferred to another that might have different endianness. The arguments are:
code A compiled regular expression
extra Points to an associated pcre[16|32]_extra structure,
or is NULL
tables Pointer to character tables, or NULL to
set the built-in default
The result is 0 for success, a negative PCRE_ERROR_xxx value otherwise.
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.
The man pages pcre16_pattern_to_host_byte_order(3) and pcre32_pattern_to_host_byte_order(3) are aliases of pcre_pattern_to_host_byte_order(3).
