strtrim − remove leading and trailing whitespace
#include <publib.h>
char *strtrim(char *s);
strtrim removes all whitespace characters from the beginning and the end of a string. As whitespace is counted everything for which isspace(3) returns true.
strtrim returns its argument.
To remove whitespace from the beginning and end of all lines, you might do the following:
#include <publib.h>
int main(void) {
|
char line[512]; |
|||
|
while (fgets(line, sizeof(line), stdio) != NULL) { |
|||
|
strtrim(line); |
|||
|
printf("%s", line); |
|||
|
} |
|||
|
return 0; |
}
publib(3), strrtrim(3), strltrim(3), isspace(3)
