sscanf
int sscanf (const char sourceString[], const char formatString[], ...);
Purpose
Converts input from the specified source string into a series of values according to the specifiers in formatString. If copying takes place between objects that overlap, the behavior is undefined.
Parameters
| Input | ||||
| Name | Type | Description | ||
| sourceString | const char [] | Contains a pointer to the string that the input to be converted is obtained from. | ||
| formatString | const char [] |
Contains the format string that specifies the admissible input sequences and how they are converted for
assignment. Use standard ANSI C format specifiers. If insufficient arguments exist for the format, the behavior is undefined. If the format is exhausted
while arguments remain, the excess arguments are evaluated but are otherwise ignored.
