Conversion of character string to integer (long int type) and storing pointer in last character string

[Classification]

Standard library

[Syntax]

#include <stdlib.h>

long int __far strtol(const char __near *nptr, char __near * __near *endptr, int base);

long int __far _COM_strtol_ff(const char __far *nptr, char __far * __far *endptr, int base);

[Return value]

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.

[Description]

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.
