StrToULongLong
int StrToULongLong (const char string[], unsigned long long *unsignedIntegerValue);
Purpose
Attempts to convert a nul–terminated string to an unsigned 64-bit integer value.
If the bytes in the nul–terminated string contain a valid ASCII decimal representation of an unsigned 64-bit integer value, and there are no extraneous non–white–space characters in the string, this function returns 1. Otherwise, this function returns 0.
This function is similar to the C library strtoull function except in how extraneous characters are treated.
Parameters
| Input | ||
| Name | Type | Description |
| string | const char[] | A nul–terminated string. |
| Output | ||
| Name | Type | Description |
| unsignedIntegerValue | unsigned long long | The unsigned 64-bit integer value represented by the characters in string. If the characters in string are not a valid ASCII decimal representation of an unsigned 64-bit integer value, or there are extraneous characters, this parameter is not modified. |
Return Value
| Name | Type | Description |
| success | int | If the bytes in the nul–terminated string contain a valid ASCII decimal representation of an unsigned 64-bit integer value, and there are no extraneous non–white–space characters in the string, this function returns 1. Otherwise, this function returns 0. |
