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