Hello all !
Could someone throw some light on whether there's a limit to the number of characters contained in the command string that is passed to the system() call in C.

Thanks. (4 Replies)

<string.h>(P) POSIX Programmer's Manual <string.h>(P)
NAME
string.h - string operations
SYNOPSIS
#include <string.h>
DESCRIPTION
Some of the functionality described on this reference page extends the ISO C standard. Applications shall define the appropriate feature
test macro (see the System Interfaces volume of IEEE Std 1003.1-2001, Section 2.2, The Compilation Environment) to enable the visibility of
these symbols in this header.
The <string.h> header shall define the following:
NULL Null pointer constant.
size_t As described in <stddef.h> .
The following shall be declared as functions and may also be defined as macros. Function prototypes shall be provided.
void *memccpy(void *restrict, const void *restrict, int, size_t);
void *memchr(const void *, int, size_t);
int memcmp(const void *, const void *, size_t);
void *memcpy(void *restrict, const void *restrict, size_t);
void *memmove(void *, const void *, size_t);
void *memset(void *, int, size_t);
char *strcat(char *restrict, const char *restrict);
char *strchr(const char *, int);
int strcmp(const char *, const char *);
int strcoll(const char *, const char *);
char *strcpy(char *restrict, const char *restrict);
size_t strcspn(const char *, const char *);
char *strdup(const char *);
char *strerror(int);
int *strerror_r(int, char *, size_t);
size_t strlen(const char *);
char *strncat(char *restrict, const char *restrict, size_t);
int strncmp(const char *, const char *, size_t);
char *strncpy(char *restrict, const char *restrict, size_t);
char *strpbrk(const char *, const char *);
char *strrchr(const char *, int);
size_t strspn(const char *, const char *);
char *strstr(const char *, const char *);
char *strtok(char *restrict, const char *restrict);
char *strtok_r(char *, const char *, char **);
size_t strxfrm(char *restrict, const char *restrict, size_t);
Inclusion of the <string.h> header may also make visible all symbols from <stddef.h>.
The following sections are informative.
APPLICATION USAGE
None.
