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)
