static Eina_Bool eina_dbl_exact | ( | double | a, |
double | b | ||
) | [static] |
Warningless comparison of doubles using ==.
- Parameters:
-
[in] a First member to compare [in] b Second member to compare
- Returns:
true
if two doubles match
- Since (EFL) :
- 1.19
const char* eina_environment_home_get | ( | void | ) |
Returns the content of the environment referred by HOME on this system.
- Returns:
- A temporary string to the content referred by HOME on this system.
- Note:
- The result of this call is highly system dependent and you better use it instead of the naive getenv("HOME").
- Since (EFL) :
- 1.15
- Since :
- 3.0
const char* eina_environment_tmp_get | ( | void | ) |
Returns the content of the environment referred as TMPDIR on this system.
- Returns:
- A temporary string to the content referred by TMPDIR on this system.
- Note:
- The result of this call is highly system dependent and you better use it instead of the naive getenv("TMPDIR").
- Since (EFL) :
- 1.15
- Since :
- 3.0

- Parameters:
-
[in] a First member to compare [in] b Second member to compare
- Returns:
true
if two floats match
