Header file
Defined in SDL3/SDL_stdinc.h
Overview
If str starts with whitespace, then those whitespace characters are skipped before attempting to parse the number.
If the parsed number does not fit inside an unsignedlonglong , the result is clamped to the maximum representable unsignedlonglong value.
Function parameters
- str
-
The null-terminated string to read. Must not be NULL.
- endp
-
If not NULL, the address of the first invalid character (i.e. the next character after the parsed number) will be written to this pointer.
- base
-
The base of the integer to read. Supported values are 0 and 2 to 36 inclusive. If 0, the base will be inferred from the number's prefix (0x for hexadecimal, 0 for octal, decimal otherwise).
Return value
Returns the parsed unsignedlonglong , or 0 if no number could be parsed.
Thread safety
It is safe to call this function from any thread.
