Macro Definition Documentation

assign_double_to_cmocka_value

#define assign_double_to_cmocka_value

(

value

)

Value:

    (CMockaValueData)                        \
    {                                        \
        .real_val = ((double)(value))        \
    }

Assign a double floating point value to CMockaValueData.

assign_float_to_cmocka_value

#define assign_float_to_cmocka_value

(

value

)

Value:

    (CMockaValueData)                        \
    {                                        \
        .float_val = ((float)(value))        \
    }

Assign a floating point value to CMockaValueData.

assign_int_to_cmocka_value

#define assign_int_to_cmocka_value

(

value

)

Value:

    (CMockaValueData)                     \
    {                                     \
        .int_val = (value)                \
    }

Assign an integer value to CMockaValueData.

assign_uint_to_cmocka_value

#define assign_uint_to_cmocka_value

(

value

)

Value:

    (CMockaValueData)                      \
    {                                      \
        .uint_val = (value)                \
    }

Assign an unsigned integer value to CMockaValueData.

cast_int_to_cmocka_value

#define cast_int_to_cmocka_value

(

value

)

Value:

    (CMockaValueData)                   \
    {                                   \
        .uint_val = (uintmax_t)(value)  \
    }

Perform a cast from an integer to CMockaValueData.

For backwards compatibility reasons, this explicitly casts to uintmax_t. For most compilers, this will suppress warnings about passing float/intmax_t to this macro.

cast_ptr_to_cmocka_value

#define cast_ptr_to_cmocka_value

(

value

)

Value:

    (CMockaValueData)                   \
    {                                   \
        .ptr = (value)                  \
    }

Perform a cast from a pointer to CMockaValueData.

cast_ptr_to_uintmax_type

#define cast_ptr_to_uintmax_type

(

value

)

Value:

    ((uintmax_t)(uintptr_t)(value))

cast_to_double_type

#define cast_to_double_type

(

value

)

Value:

    ((double)(value))

cast_to_float_type

#define cast_to_float_type

(

value

)

Value:

    ((float)(value))

cast_to_intmax_type

#define cast_to_intmax_type

(

value

)

Value:

    ((intmax_t)(value))

cast_to_uintmax_type

#define cast_to_uintmax_type

(

value

)

Value:

    ((uintmax_t)(value))

cast_to_void_pointer

#define cast_to_void_pointer

(

ptr

)

Value:

    ((void *)(uintptr_t)(ptr))

Perform cast to void pointer.

ISO C forbids conversion between function pointers and void*. This macro provides a portable way to perform such conversions by casting through uintptr_t, which is allowed by POSIX and works on all practical platforms.

cmocka_tostring

#define cmocka_tostring

(

val

)

Value:

#val
