I don't get what you want to do here. #define is interpreted at compile time. You can't change limit_fmt at runtime anywhere.


You are on Solaris, or why you don't like the "%.0d%s" solution? It should work with Solaris too as "%.0lu%s" (maybe it's even possible to leave the 0 out, as a missing specification is interpreted as zero):

Assembling the format string at runtime means to:

#include <stdio.h>
#include <string.h>
#define FMT(x) (x<0)?"%05d":"%+10d"

int main(void)
{
    char      line[255];
    int       value_int;

    value_int = 42;

    strcpy(line, "The value is = ");
    strcat(line, FMT(value_int));
    strcat(line, "\n");

    printf(line, value_int);


    value_int = -1;

    strcpy(line, "The value is = ");
    strcat(line, FMT(value_int));
    strcat(line, "\n");

    printf(line, value_int);

    return (0);
}
