Conversion of character string to integer (long int type) and storing pointer to last character string
long int __far strtol(const char __near *nptr, char __near * __near *endptr, int base); (C90)
long int __far strtol(const char __near * restrict nptr, char __near * __near * restrict endptr, int base); (C99) [V1.07 or later]
long int __far _COM_strtol_ff(const char __far *nptr, char __far * __far *endptr, int base); (C90)
long int __far _COM_strtol_ff(const char __far * restrict nptr, char __far * __far * restrict endptr, int base); (C99) [V1.07 or later]
Returns the converted value if the partial character string could be converted. If it could not, 0 is returned.
If an overflow occurs, strtol returns LONG_MAX or LONG_MIN and sets macro ERANGE to global variable errno.
This function skips 0 or more columns of white-space characters (character which makes the isspace function true) from the start of the string indicated by nptr, and converts the string from the next character into a long int-type representation. If base is 0, the value is interpreted as the C radix representation. If base is between the range of 2 and 36, the value is interpreted as a radix. When endptr is not the null pointer, the pointer to the remaining strings that were not converted is set to endptr.
