Defined in SDL3/SDL_stdinc.h

#include "SDL3/SDL.h"

long SDL_strtol(const char *str, char **endp, int base);

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 a long , the result is clamped to the minimum and maximum representable long values.

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).

Returns the parsed long , or 0 if no number could be parsed.

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
