代码：

#include <stdio.h>
#include <string.h>

const char *p = "  [ session  ]  ";

int main() {
    char *ps1 = NULL;
    char *ps2 = NULL;
    char s[64] = {0};

    ps1 = p + strspn(p, "[ 	");
    printf("%s
", ps1);
    ps2 = ps1 + strcspn(ps1, "	 ]");
    printf("%s
", ps2);

    strncpy(s, ps1, ps2-ps1);
    printf("%s
", s); 

    return 0;
}

结果：

session  ]
  ]
session
