The string utilities module is a collection of string conversion helpers to convert between integer and strings.

◆ cy_generic_string_to_unsigned()
| uint32_t cy_generic_string_to_unsigned |
( |
const char * |
str | ) |
|
Convert a decimal or hexidecimal string to an integer.
- Parameters
-
| [in] | str | The string containing the value. |
- Returns
- The value represented by the string.
◆ cy_string_to_signed()
| uint8_t cy_string_to_signed |
( |
const char * |
string, |
|
|
uint16_t |
str_length, |
|
|
int32_t * |
value_out, |
|
|
uint8_t |
is_hex |
|
) |
| |
Converts a decimal/hexidecimal string (with optional sign) to a signed long int Better than strtol or atol or atoi because the return value indicates if an error occurred.
- Parameters
-
| [in] | string | : The string buffer to be converted |
| [in] | str_length | : The maximum number of characters to process in the string buffer |
| [out] | value_out | : The unsigned in that will receive value of the the decimal string |
| [in] | is_hex | : 0 = Decimal string, 1 = Hexidecimal string |
- Returns
- the number of characters successfully converted (including sign). i.e. 0 = error

|
) |
| |
Converts a decimal/hexidecimal string to an unsigned long int Better than strtol or atol or atoi because the return value indicates if an error occurred.
- Parameters

| [out] | value_out | : The unsigned in that will receive value of the the decimal string |
| [in] | is_hex | : 0 = Decimal string, 1 = Hexidecimal string |
- Returns
- the number of characters successfully converted. i.e. 0 = error
