strtoimax Function

Convert string to integer value.

Include

<inttypes.h>

Prototype

intmax_t strtoimax(const char * restrict nptr, char ** restrict endptr, int base);

Argument

nptr

the string to attempt to convert

endptr

pointer to the remainder of the string that was not converted

base

The base of the conversion

Return Value

The converted value, or 0 if the conversion could not be performed.

Remarks

The strtoimax function attempts to convert the first part of the string pointed to by nptr to an intmax_t integer value.

Example

#include <inttypes.h>
#include <stdio.h>

int main(void)
{ 
  char * string = "-1234abcd";
  char * final;
  intmax_t result;
  
  result = strtoimax(string, &final, 10);
  printf("The integer conversion of the string \"%s\" is %" PRIdMAX "; final string part is \"%s\"\n", string, result, final);
}

Example Output

The integer conversion of the string "-1234abcd" is -1234; final string part is "abcd"
