pREPC+ System Calls atol
atol Converts a string to a long integer.
#include
long atol(
const char *nptr /* string */
)
Description
Arguments
Return Value
Error Codes
The atol() function converts the initial part of the string pointed to by nptr to a
long int representation. Leading white spaces are ignored. The conversion
terminates when a nondigit character is detected. If the first non-whitespace
character is not a digit, a value of 0 is returned.
Except for the behavior on error, this call is equivalent to:
strtol(str, (char **)NULL, 10);
nptr Points to the string to be converted.
This function returns the converted value. If an error occurs, errno is set to
indicate the condition.
