Define Documentation

#define apreq_attr_to_type ( T,
A,
 )     ( (T*) ((char*)(P)-offsetof(T,A)) )

Parameters:
T type
A attribute
P XXX

#define APREQ_CHARSET_BIT   0

#define APREQ_CHARSET_MASK   255

#define APREQ_COOKIE_HTTPONLY_BIT   14

#define APREQ_COOKIE_HTTPONLY_MASK   1

#define APREQ_COOKIE_SECURE_BIT   13

#define APREQ_COOKIE_SECURE_MASK   1

#define APREQ_COOKIE_VERSION_BIT   11

#define APREQ_COOKIE_VERSION_MASK   3

#define APREQ_DECLARE (  )     APR_DECLARE(d)

The public APREQ functions are declared with APREQ_DECLARE(), so they may use the most appropriate calling convention. Public APR functions with variable arguments must use APR_DECLARE_NONSTD().

Remarks:
Both the declaration and implementations must use the same macro. APREQ_DECLARE(rettype) apeq_func(args)
Examples:
/home/issac/asf/svn/v2_13/include/apreq.h.

#define APREQ_DECLARE_DATA

The public APREQ variables are declared with APREQ_DECLARE_DATA. This assures the appropriate indirection is invoked at compile time.

See also:
APREQ_DECLARE

APREQ_DECLARE_NONSTD

Remarks:
Note that the declaration and implementations use different forms, but both must include the macro. extern APREQ_DECLARE_DATA type apr_variable;
APREQ_DECLARE_DATA type apr_variable = value;

#define APREQ_DECLARE_NONSTD (  )     APR_DECLARE_NONSTD(d)

APEQ_DECLARE_NONSTD(rettype) apr_func(args, ...);

#define APREQ_DEFAULT_BRIGADE_LIMIT   (256 * 1024)

Maximum number of bytes mod_apreq2 will let accumulate within the heap-buckets in a brigade. Excess data will be spooled to an appended file bucket

See also:
ap_set_brigade_read_limit

#define APREQ_DEFAULT_NELTS   8

Number of elements in the initial apr_table

See also:
apr_table_make

#define APREQ_DEFAULT_READ_BLOCK_SIZE   (64 * 1024)

Read chucks of data in 64k blocks from the request

#define APREQ_DEFAULT_READ_LIMIT   (64 * 1024 * 1024)

Maximum number of bytes mod_apreq2 will send off to libapreq2 for parsing. mod_apreq2 will log this event and subsequently remove itself from the filter chain.

See also:
ap_set_read_limit

#define APREQ_FLAGS_GET ( f,
name   )     (((f) >> name##_BIT) & name##_MASK)

Get specified bit f in bitfield name

#define APREQ_FLAGS_OFF ( f,
name   )     ((f) &= ~(name##_MASK << name##_BIT))

Check to see if specified bit f is off in bitfield name

#define APREQ_FLAGS_ON ( f,
name   )     ((f) |= (name##_MASK << name##_BIT))

Check to see if specified bit f is on in bitfield name

#define APREQ_FLAGS_SET ( f,
name,
value   ) 

Value:

((f) = (((f) & ~(name##_MASK << name##_BIT))        \
            | ((name##_MASK & (value)) << name##_BIT)))
Set specified bit f in bitfield name to value Note the below BIT/Mask defines are used sans the _BIT, _MASK because of the this define's ##_MASK, ##_BIT usage. Each come in a pair

#define APREQ_TAINTED_BIT   8

#define APREQ_TAINTED_MASK   1


Enumeration Type Documentation

Character encodings.

Expiration date format

Enumerator:
APREQ_EXPIRES_HTTP  Use date formatting consistent with RFC 2616
APREQ_EXPIRES_NSCOOKIE  Use format consistent with Netscape's Cookie Spec

Join type

Enumerator:
APREQ_JOIN_AS_IS  Join the strings without modification
APREQ_JOIN_ENCODE  Url-encode the strings before joining them
APREQ_JOIN_DECODE  Url-decode the strings before joining them
APREQ_JOIN_QUOTE  Quote the strings, backslashing existing quote marks.

Match type

Enumerator:
APREQ_MATCH_FULL  Full match only.
APREQ_MATCH_PARTIAL  Partial matches are ok.


Function Documentation

apr_status_t apreq_initialize ( apr_pool_t pool  ) 

Initialize libapreq2. Applications (except apache modules using mod_apreq) should call this exactly once before they use any libapreq2 modules. If you want to modify the list of default parsers with apreq_register_parser(), please use apreq_pre_initialize() and apreq_post_initialize() instead.

Parameters:
pool a base pool persisting while libapreq2 is used
Remarks:
after you detroy the pool, you have to call this function again with a new pool if you still plan to use libapreq2
Examples:
/home/issac/asf/svn/v2_13/include/apreq.h.

apr_status_t apreq_post_initialize ( apr_pool_t pool  ) 

Post-initialize libapreq2. Applications (except apache modules using mod_apreq2) should this exactly once before they use any libapreq2 modules for parsing.

Parameters:
pool the same pool that was used in apreq_pre_initialize().
Examples:
/home/issac/asf/svn/v2_13/include/apreq.h.

apr_status_t apreq_pre_initialize ( apr_pool_t pool  ) 

Pre-initialize libapreq2. Applications (except apache modules using mod_apreq2) should call this exactly once before they register custom parsers with libapreq2. mod_apreq2 does this automatically during the post-config phase, so modules that need call apreq_register_parser should create a post-config hook using APR_HOOK_MIDDLE.

Parameters:
pool a base pool persisting while libapreq2 is used
Remarks:
after you detroyed the pool, you have to call this function again with a new pool if you still plan to use libapreq2
Examples:
/home/issac/asf/svn/v2_13/include/apreq.h.

static APR_INLINE void apreq_value_table_add ( const apreq_value_t v,
apr_table_t t 
) [static]

Adds the specified apreq_value_t to the apr_table_t.

Parameters:
v value to add
t add v to this table
Returns:
void
@ see apr_table_t
