- talloc string allocation and manipulation functions.
The talloc debugging support functions
To aid memory debugging, talloc contains routines to inspect the currently allocated memory hierarchy.

Duplicate a string into a talloc chunk.
_PUBLIC_ char * talloc_strdup_append (char *s, const char *a)
Append a string to given string.
_PUBLIC_ char * talloc_strdup_append_buffer (char *s, const char *a)
Append a string to a given buffer.
_PUBLIC_ char * talloc_strndup (const void *t, const char *p, size_t n)
Duplicate a length-limited string into a talloc chunk.
_PUBLIC_ char * talloc_strndup_append (char *s, const char *a, size_t n)
Append at most n characters of a string to given string.
_PUBLIC_ char * talloc_strndup_append_buffer (char *s, const char *a, size_t n)
Append at most n characters of a string to given buffer.
_PUBLIC_ char * talloc_vasprintf (const void *t, const char *fmt, va_list ap)
Format a string given a va_list.
_PUBLIC_ char * talloc_vasprintf_append (char *s, const char *fmt, va_list ap)
Format a string given a va_list and append it to the given destination string.
_PUBLIC_ char * talloc_vasprintf_append_buffer (char *s, const char *fmt, va_list ap)
Format a string given a va_list and append it to the given destination buffer.
_PUBLIC_ char * talloc_asprintf (const void *t, const char *fmt,...)
Format a string.
_PUBLIC_ char * talloc_asprintf_append (char *s, const char *fmt,...)
Append a formatted string to another string.
_PUBLIC_ char * talloc_asprintf_append_buffer (char *s, const char *fmt,...)
Append a formatted string to another string.
talloc string allocation and manipulation functions.
Format a string. This function is the talloc equivalent of the C library function asprintf(3).
This functions sets the name of the new pointer to the new string. This is equivalent to:
talloc_set_name_const(ptr, ptr)
Parameters
Returns
Append a formatted string to another string. This function appends the given formatted string to the given string. Use this variant when the string in the current talloc buffer may have been truncated in length.
This functions sets the name of the new pointer to the new string. This is equivalent to:
talloc_set_name_const(ptr, ptr)
If s == NULL then new context is created.
Parameters
Returns
Append a formatted string to another string. This is a more efficient version of talloc_asprintf_append(). It determines the length of the destination string by the size of the talloc context.
Use this very carefully as it produces a different result than talloc_asprintf_append() when a zero character is in the middle of the destination string.
char *str_a = talloc_strdup(NULL, "hello world");
char *str_b = talloc_strdup(NULL, "hello world");
str_a[5] = str_b[5] = ' '
char *app = talloc_asprintf_append(str_a, "%s", ", hello");
char *buf = talloc_strdup_append_buffer(str_b, "%s", ", hello");
printf("%s, app); // hello, hello (app = "hello, hello")
printf("%s, buf); // hello (buf = "hello world, hello")
If s == NULL then new context is created.
Parameters
Returns
See also
talloc_asprintf_append()
Duplicate a string into a talloc chunk. This function is equivalent to:
ptr = talloc_size(ctx, strlen(p)+1); if (ptr) memcpy(ptr, p, strlen(p)+1);
This functions sets the name of the new pointer to the passed string. This is equivalent to:
talloc_set_name_const(ptr, ptr)
Parameters
Returns
Append a string to given string. The destination string is reallocated to take strlen(s) + strlen(a) + 1 characters.
This functions sets the name of the new pointer to the new string. This is equivalent to:
talloc_set_name_const(ptr, ptr)
If s == NULL then new context is created.
Parameters
Returns

talloc_strdup_append_buffer()
Append a string to a given buffer. This is a more efficient version of talloc_strdup_append(). It determines the length of the destination string by the size of the talloc context.
Use this very carefully as it produces a different result than talloc_strdup_append() when a zero character is in the middle of the destination string.
char *str_a = talloc_strdup(NULL, "hello world");
char *str_b = talloc_strdup(NULL, "hello world");
str_a[5] = str_b[5] = ' '
char *app = talloc_strdup_append(str_a, ", hello");
char *buf = talloc_strdup_append_buffer(str_b, ", hello");
printf("%s, app); // hello, hello (app = "hello, hello")
printf("%s, buf); // hello (buf = "hello world, hello")
If s == NULL then new context is created.
Parameters
Returns

talloc_strdup_append()
talloc_array_length()
Duplicate a length-limited string into a talloc chunk. This function is the talloc equivalent of the C library function strndup(3).
This functions sets the name of the new pointer to the passed string. This is equivalent to:
talloc_set_name_const(ptr, ptr)
Parameters
Returns
Append at most n characters of a string to given string. The destination string is reallocated to take strlen(s) + strnlen(a, n) + 1 characters.
This functions sets the name of the new pointer to the new string. This is equivalent to:
talloc_set_name_const(ptr, ptr)
If s == NULL then new context is created.
Parameters
Returns
See also
talloc_strndup_append_buffer()
Append at most n characters of a string to given buffer. This is a more efficient version of talloc_strndup_append(). It determines the length of the destination string by the size of the talloc context.
Use this very carefully as it produces a different result than talloc_strndup_append() when a zero character is in the middle of the destination string.
char *str_a = talloc_strdup(NULL, "hello world");
char *str_b = talloc_strdup(NULL, "hello world");
str_a[5] = str_b[5] = ' '
char *app = talloc_strndup_append(str_a, ", hello", 7);
char *buf = talloc_strndup_append_buffer(str_b, ", hello", 7);
printf("%s, app); // hello, hello (app = "hello, hello")
printf("%s, buf); // hello (buf = "hello world, hello")
If s == NULL then new context is created.
Parameters
Returns

talloc_strndup_append()
talloc_array_length()
Format a string given a va_list. This function is the talloc equivalent of the C library function vasprintf(3).
This functions sets the name of the new pointer to the new string. This is equivalent to:
talloc_set_name_const(ptr, ptr)
Parameters
Returns
Format a string given a va_list and append it to the given destination string.
Parameters
Returns
See also
Format a string given a va_list and append it to the given destination string.
Good for gradually accumulating output into a string buffer. Appends at the end of the string.
Format a string given a va_list and append it to the given destination buffer.
Parameters
Returns
See also
Format a string given a va_list and append it to the given destination buffer.
Always appends at the end of the talloc'ed buffer, not the end of the string.
