Traffic Server memory allocation API.
TSrealloc(void *ptr, size_t size)¶
TSstrdup(const char *str)¶
TSstrndup(const char *str, size_t size)¶
TSstrlcpy(char *dst, const char *src, size_t size)¶
TSstrlcat(char *dst, const char *src, size_t size)¶
Traffic Server provides a number of routines for allocating and freeing
memory. These routines correspond to similar routines in the C library.
TSrealloc() behaves like the C library routine
There are two reasons to use the routines provided by Traffic Server. The
first is portability. The Traffic Server API routines behave the same on
all of Traffic Servers supported platforms. For example,
not accept an argument of
NULL on some platforms. The second reason is
that the Traffic Server routines actually track the memory allocations by
file and line number. This tracking is very efficient, is always turned
on, and is useful for tracking down memory leaks.
TSmalloc() returns a pointer to size bytes of memory allocated from the
heap. Traffic Server uses
TSmalloc() internally for memory allocations.
TSfree() to release memory allocated by
TSmalloc(); do not use
TSstrdup() returns a pointer to a new string that is a duplicate of the
string pointed to by str. The memory for the new string is allocated using
TSmalloc() and should be freed by a call to
TSstrndup() returns a pointer to a new string that is a duplicate of the
string pointed to by str but is at most size bytes long. The new
string will be NUL-terminated. This API is very useful for transforming non
NUL-terminated string values returned by APIs such as
TSMimeHdrFieldValueStringGet() into NUL-terminated string values. The
memory for the new string is allocated using
TSmalloc() and should be
freed by a call to
TSstrlcpy() copies up to size - 1 characters from the NUL-terminated
string src to dst, NUL-terminating the result.
TSstrlcat() appends the NUL-terminated string src to the end of dst. It
will append at most size -
strlen(dst) - 1 bytes, NUL-terminating the
