SDL_strtol(3) SDL3 FUNCTIONS SDL_strtol(3)

NAME

SDL_strtol - Parse a long from a string.

HEADER FILE

Defined in SDL3/SDL_stdinc.h

SYNOPSIS

#include "SDL3/SDL.h"
long SDL_strtol(const char *str, char **endp, int base);

DESCRIPTION

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.

FUNCTION PARAMETERS

The null-terminated string to read. Must not be NULL.
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.
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 long , or 0 if no number could be parsed.

THREAD SAFETY

It is safe to call this function from any thread.

AVAILABILITY

This function is available since SDL 3.1.3.
