enum StrintParseError |
String to integer conversion error.
StrintParseError strint_to_uint32 | ( | const char * | str, |
char ** | end, | ||
uint32_t * | out, | ||
uint8_t | base ) |
Converts a string to a uint32_t
[in] | str | Input string |
[out] | end | Pointer to first character after the number in input string |
[out] | out | Parse result |
[in] | base | Integer base |
Parses the number in the input string. The number may be surrounded by whitespace characters to the left and any non-digit characters to the right. What's considered a digit is determined by the input base in the following order: 0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ
. The number may be prefixed with either a +
or a -
to indicate its sign. The pointer to the first character after the leading whitespace, allowed prefixes and digits is assigned to end
.
If the input base is 0, the base is inferred from the leading characters of the number:
0x
, it's read in base 16;0
, it's read in base 8;0b
, it's read in base 2.For a description of the return codes, see StrintParseError
. If the return code is something other than StrintParseNoError
, the values at end
and out
are unaltered.
