NAME

SDL_wcstol - Parse a long from a wide string.

HEADER FILE

Defined in SDL3/SDL_stdinc.h

#include "SDL3/SDL.h"

long SDL_wcstol(const wchar_t *str, wchar_t **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 wide string to read. Must not be NULL.
endp: If not NULL, the address of the first invalid wide 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.
