on error.
This function creates a new string buffer. The passed string is used directly as the buffer, it's effectively the inverse of eina_strbuf_string_steal(). The passed string is expected to be static or otherwise on the stack rather than the malloc'd string required by eina_strbuf_manage_new_length(). To free the resources, use eina_strbuf_free().

This function removes a slice of buf
, starting at start
(inclusive) and ending at end
(non-inclusive). Both values are in bytes.

- Parameters:
-
[in,out] buf The string buffer. [in] str The text to match. [in] with The replacement string. [in] n The indexed occurrence to be replaced.
- Returns:
- EINA_TRUE on success, EINA_FALSE on failure.
This function replaces the n-th occurrence of str
in buf
with with
.
- Since :

int eina_strbuf_replace_all | ( | Eina_Strbuf * | buf, |
const char * | str, | ||
const char * | with | ||

[in,out] buf The string buffer. [in] str The text to match. [in] with The replacement string.
- Returns:
- Number of replacements made, or
0
on failure.
This function replaces all the occurrences of str
in buf
with the string with
.

Eina_Bool eina_strbuf_replace_last | ( | Eina_Strbuf * | buf, |
const char * | str, | ||
const char * | with | ||
) |
Replaces the last occurrence of a substring with another string.
- Parameters:
-
[in,out] buf The string buffer. [in] str The text to match. [in] with The replacement string.
- Returns:
- EINA_TRUE on success, EINA_FALSE on failure.
This function replaces the last occurrence of str
in buf
with with
.
void eina_strbuf_reset | ( | Eina_Strbuf * | buf | ) |
Resets a string buffer.
- Parameters:
-
[in,out] buf The string buffer.
This function resets buf:
the buffer len is set to 0, and the string data is set to '\0'. No memory is freed.
- Since :
- 2.3.1
- Examples:
- eina_strbuf_01.c.
void eina_strbuf_rtrim | ( | Eina_Strbuf * | buf | ) |
Right trims the string buffer.
- Parameters:
-
[in,out] buf The string buffer.
This function removes whitespace at the end of the buffer's string.
- Since :
- 2.3.1
Eina_Rw_Slice eina_strbuf_rw_slice_get | ( | const Eina_Strbuf * | buf | ) |
Gets a read-write slice of the buffer contents.
- Parameters:
-
[in] buf The string buffer.
- Returns:
- A read-write slice for the current contents. It may become invalid as soon as the
buf
is changed, such as through calls like eina_strbuf_append() or eina_strbuf_remove().
- Since (EFL) :
- 1.19.0
Eina_Slice eina_strbuf_slice_get | ( | const Eina_Strbuf * | buf | ) |
Gets a read-only slice of the buffer contents.
- Parameters:
-
[in] buf The string buffer.
- Returns:
- A read-only slice of the current contents. It may become invalid as soon as
buf
is changed.
- Since (EFL) :
- 1.19
void eina_strbuf_string_free | ( | Eina_Strbuf * | buf | ) |
Frees the contents of a string buffer but not the buffer.
- Parameters:
-
[in,out] buf The string buffer.
This function frees the string contained in buf
without freeing buf
.
- Since :
- 2.3.1
const char* eina_strbuf_string_get | ( | const Eina_Strbuf * | buf | ) |
Retrieves a pointer to the contents of a string buffer.
- Parameters:
-
[in] buf The string buffer.
- Returns:
- The current string in the string buffer.
This function returns the string contained in buf
. The returned value must not be modified and will no longer be valid if buf
is modified. In other words, calling eina_strbuf_append() or similar functions will make this pointer invalid. The pointer returned by this function must not be freed.

char* eina_strbuf_string_steal | ( | Eina_Strbuf * | buf | ) |
Steals the contents of a string buffer.
- Parameters:
-
[in,out] buf The string buffer.
- Returns:
- The string that was contained in
buf
.
This function returns the string contained in buf
. buf
is then initialized and does not own the returned string anymore. The caller must release the memory of the returned string by calling free().

void eina_strbuf_tolower | ( | Eina_Strbuf * | buf | ) |

- Parameters:
-
