apr_int64_t apr_atoi64 ( const char *  buf  ) 

parse a base-10 numeric string into a 64-bit numeric value. Equivalent to apr_strtoi64(buf, (char**)NULL, 10).

引数:
buf The string to parse
戻り値:
The numeric value of the string

char* apr_collapse_spaces ( char *  dest,
const char *  src 
)

Strip spaces from a string

引数:
dest The destination string. It is okay to modify the string in place. Namely dest == src
src The string to rid the spaces from.
戻り値:
The destination string, dest.

char char* apr_cpystrn ( char *  dst,
const char *  src,
apr_size_t  dst_size 
)

Copy up to dst_size characters from src to dst; does not copy past a NUL terminator in src, but always terminates dst with a NUL regardless.

引数:
dst The destination string
src The source string
dst_size The space available in dst; dst always receives NUL termination, so if src is longer than dst_size, the actual number of characters copied is dst_size - 1.
戻り値:
Pointer to the NUL terminator of the destination string, dst
意見:
 Note the differences between this function and strncpy():
  1) strncpy() doesn't always NUL terminate; apr_cpystrn() does.
  2) strncpy() pads the destination string with NULs, which is often 
     unnecessary; apr_cpystrn() does not.
  3) strncpy() returns a pointer to the beginning of the dst string;
     apr_cpystrn() returns a pointer to the NUL terminator of dst, 
     to allow a check for truncation.

The new string

char* apr_pstrcat ( apr_pool_t p,

Concatenate multiple strings, allocating memory out a pool

引数:
p The pool to allocate out of
... The strings to concatenate. The final string must be NULL
戻り値:
The new string

char* apr_pstrcatv ( apr_pool_t p,
const struct iovec *  vec,
apr_size_t  nvec,
apr_size_t *  nbytes 
)

Concatenate multiple strings specified in a writev-style vector

引数:

nvec The number of strings to concatenate
nbytes (output) strlen of new string (pass in NULL to omit)
戻り値:
The new string

char* apr_pstrdup ( apr_pool_t p,
const char *  s 
)

duplicate a string into memory allocated out of a pool

引数:
p The pool to allocate out of
s The string to duplicate
戻り値:
The new string

char* apr_pstrmemdup ( apr_pool_t p,
const char *  s,
apr_size_t  n 
)

Create a null-terminated string by making a copy of a sequence of characters and appending a null byte

引数:
p The pool to allocate out of
s The block of characters to duplicate
n The number of characters to duplicate
戻り値:
The new string
意見:
This is a faster alternative to apr_pstrndup, for use when you know that the string being duplicated really has 'n' or more characters. If the string might contain fewer characters, use apr_pstrndup.

char* apr_pstrndup ( apr_pool_t p,
const char *  s,
apr_size_t  n 
)

duplicate the first n characters of a string into memory allocated out of a pool; the new string will be null-terminated

引数:
p The pool to allocate out of
s The string to duplicate
n The number of characters to duplicate
戻り値:
The new string

char* apr_pvsprintf ( apr_pool_t p,
const char *  fmt,
va_list  ap 
)

printf-style style printing routine. The data is output to a string allocated from a pool

引数:
p The pool to allocate out of
fmt The format of the string
ap The arguments to use while printing the data
戻り値:
The new string

char* apr_strfsize ( apr_off_t  size,
char *  buf 
)

Format a binary size (magnitiudes are 2^10 rather than 10^3) from an apr_off_t, as bytes, K, M, T, etc, to a four character compacted human readable string.

引数:
size The size to format
buf The 5 byte text buffer (counting the trailing null)
戻り値:
The buf passed to apr_strfsize()
意見:
All negative sizes report ' - ', apr_strfsize only formats positive values.

int apr_strnatcasecmp ( char const *  a,
char const *  b 
)

Do a natural order comparison of two strings ignoring the case of the strings.

引数:
a The first string to compare
b The second string to compare
戻り値:
Either <0, 0, or >0. If the first string is less than the second this returns <0, if they are equivalent it returns 0, and if the first string is greater than second string it retuns >0.

int apr_strnatcmp ( char const *  a,
char const *  b 
)

Do a natural order comparison of two strings.

引数:
a The first string to compare
b The second string to compare
戻り値:
Either <0, 0, or >0. If the first string is less than the second this returns <0, if they are equivalent it returns 0, and if the first string is greater than second string it retuns >0.

apr_status_t apr_strtoff ( apr_off_t *  offset,

end A pointer to the end of the valid character in buf. If not NULL, it is set to the first invalid character in buf.
base A numeric base in the range between 2 and 36 inclusive, or 0. If base is zero, buf will be treated as base ten unless its digits are prefixed with '0x', in which case it will be treated as base 16.

apr_int64_t apr_strtoi64 ( const char *  buf,
char **  end,
int  base 
)

parse a numeric string into a 64-bit numeric value

引数:
buf The string to parse. It may contain optional whitespace, followed by an optional '+' (positive, default) or '-' (negative) character, followed by an optional '0x' prefix if base is 0 or 16, followed by numeric digits appropriate for base.
end A pointer to the end of the valid character in buf. If not NULL, it is set to the first invalid character in buf.
base A numeric base in the range between 2 and 36 inclusive, or 0. If base is zero, buf will be treated as base ten unless its digits are prefixed with '0x', in which case it will be treated as base 16.

const char *  sep,
char **  last 
)

Split a string into separate null-terminated tokens. The tokens are delimited in the string by one or more characters from the sep argument.

sep The set of delimiters
last Internal state saved by apr_strtok() between calls.
